Simplicity with Flare

electricbeach is a cottage industry which wishes to remain as such, created by one Steve Jay and his passion for the FRUGEL_1Frugal Horn design and its capabilities for natural sounding music reproduction based on simplicity.

With frugal being the overriding brief for the project, Steve has created a system based around the well known Frugal Horn Mk3 design and added an amplifier from Chinese company Dared (a tube based triode preamplifier married to a class D power amplifier) plus his own high purity copper configuration of speaker cables. Simply add a source such as an OPPO universal player or music streamer and you have a minimalist system which can be tailored style-wise to suit your own personal decor and colour schemes.

After being made aware of this speaker/amp combo becoming available for review I quickly showed interest in them and was put in contact with Steve Jay from electricbeach. We had a lengthy chat on the telephone about his aspirations and enthusiasm for the system with him stating that “The system is capable of great musical appeal and that the amplifier is equipped with 6 channels, so has the potential to be built upon with matching rears and a centre speaker”. This however is not the basis for a review for Hifi Pig as we tend to focus on two channel reproduction; although it’s a very interesting addition should the buyer wish to expand the system to cover movies and TV.

I was initially dubious as I, like others, don’t really associate Hifi with Home Cinema, but Steve suggested “It’s an added benefit, not a compromise. The amplifier has no processing and is purely pre amp plus 5 channel power amp, a source would have to do all the processing, it is not anything like a AV based receiver amp, yet can accommodate 5 speakers and a sub (passive or powered)”.

The Frugel3 speakers themselves can be finished in any gloss painted finishes you like, satin or matt, with a combination of a large range of leather and or wood finishes.

Horns by their very nature and design have some wonderful attributes and some areas which can be a partial compromise. Like a lot of other speakers there are always pros and cons and we often audition and buy speakers and relevant components to suit our musical tastes and listening rooms. Horn speakers or single driver speakers tend to have a gorgeous midrange, the top end can be a little rolled off and the bass can be a little loose and lumpy.

The Frugel3 is a hybrid, adopting a part horn and part transmission line design. I’ve never been a great fan of transmission line speakers due to an over blown bass and a long slow extended booming character to their bottom end. The Frugel3 has the first part of its internal chambers constructed to utilise the transmission design and the lower part is based on a horn speaker with a rear bottom mouth which allows the driver to breathe and recreate lower frequencies.

Stuart and Linette had the opportunity to have a pair of the TSAE Evince Loudspeakers in the house for a few days for review. Evince LoudspeakersThey are a really interesting design that takes the traditional transmission line design for loudspeakers and turns it into something that looks visually stunning. Visually stunning they may be but what did they sound like? Read the two reviews here.

There are two reviews of the TSAE Evince Loudspeakers here. One was done by Stuart and one by Linette. Both were written completely independently and without sharing of notes, though we did listen together – hey, we’re married.

SCHERER, the brand of TSAE (Thomas Scherer Audio Engineering) and the owner  Thomas Scherer is a German OLYMPUS DIGITAL CAMERAbased audio engineer who manufactures just two loudspeakers, the standmounted Elation and the floorstanding Evince which we’re looking at here.

The Evince is a transmission line design using a five inch fullrange driver. Low frequencies from the back of the full range speaker are channeled through a dedicated tube/duct and output in-phase with a forward facing driver. The shape of the transmission line used here allows the bass frequencies to travel through the line but mid-frequencies are reflected back in on themselves at the corners so that only bass frequencies are emitted from the mouth of the line. The cabinet is made from birch ply covered in a composite material that looks very sleek and well finished – it feels like very highly polished stone to the touch. The review pair were white but you can have pretty much any colour you want. It’s a very interesting and modern looking design with an interesting profile for which Thomas has been granted a patent. Basically where all other transmission lines I’ve seen hide the transmission line within a box the Evince has it unfolded and forming the body of the speaker – have a look at the photographs and you’ll see what I mean. It’s not a huge speaker, though it is deep from front to back, and it is very slim (220 x 944 x 873 mm w/h/d). The speakers weigh 25.5Kg. Purely from an aesthetic point of view I think it’s a winner, but I’m sure there will be some for whom the design is just a little too radical. They are, for all their unusual design very unobtrusive in the room and I can see them finding favour in ultra sleek and modern rooms, but also in more conventional rooms where a person wants a statement piece. Attached to the loudspeaker base is 4 cones but other feet are available to suit your particular floor type. More »

As the HiSound Audio Studio V and Roocoo Digital audio players performed well when we tested them, I was expectingNova_2 pretty good things from the Nova 1, despite it being at the cheaper end of the range retailing at around 150 US$

The promo blurb has it pegged as a ‘3 in 1 design player’, decoder, amplifier and headphones.

All I want it to do is play music to me and be simple to use when I’m out and about.

The first thing that struck me was the packaging, it was pretty cheap and flimsy an a bargain basement kind of a way, not a great first impression after seeing how the Studio V came packaged, (it looked like it was off to a gentleman’s smoking club)  however it may well be the prototype packaging which is forgivable.

The second problem became apparent when I pulled out the instructions…everything was in Chinese. ‘That’s OK, I can just switch it on and work it out!’  I’m a pretty practical gal but admittedly I don’t speak a word of Chinese and had to admit defeat after I realised I had no idea whether I was going to play an MP3 or order the set meal for 2.

My wife wandered into my music room and saw the recently unpacked turntable – “That’s very pretty, one of the best looking you’ve had” she said.  I agree, it does look mighty fine. 

The Radius 5.2 is a belt drive turntable and available in the clear acrylic that was delivered to me, or in black.  The Radiusturntable can be bought separately, but the one that was sent to me for review had a Nima unipivot arm already installed.

Roksan is well known for its turntables and started in business back in 1985 to produce the original Xerxes turntable.  The current range extends to the Xerxes.20 Plus, at £2,700 without arm.  The entry level Radius 5.2, though, usually supplied with the Nima arm retails at a more affordable £1400 or so for the bundled package.

Roksan also produce a range of electronics and loudspeakers, and the Caspian M2 amplifier has been reviewed in Hifi Pig. More »

Audio4Soul is a small company based in Greece and they produce just two items, the Xtreme 16 (tested here) and the Xtreme 16 with USB streamer. The company has an interesting philosophy and one that will appeal to a good few people I suspect – they want to produce a straightforward product that simply allows people to enjoy theOLYMPUS DIGITAL CAMERA very best sound quality at a price point that is achievable for most people. They also recognise that not all music lovers want to have boxes and boxes of hifi equipment strewn all over their living room. Of course, having a box of tricks that does it all means you have more to spend on great quality loudspeakers and this is another important aspect of the company’s philosophy.

It’s an attractive looking bit of kit and worth noting that is it is built by hand, though I’m sure it will have its detractors – the front panel is reminiscent of a piece of lab equipment. However, there is a lovely touch on the top of the unit where the ventilation grill is a cut out in the shape of a treble clef. On the front of the unit there is an SD card slot, a power switch, a small red LED screen, a switch to alternate between optical input and coaxial and a host of LEDs to let you know the status of the machine.

So what is it exactly? With the Xtreme 16 you get a16 watts per channel integrated digital amplifier that has a powered DAC onboard with a PCM/PWM converter. You can connect a CD transport (or laptop with appropriate converter) using Spdif or Toslink (the unit uses a Wolfson 8804 receiver) or you can use the front mounted SD card reader to play Ogg. Mp3 or Wav files. Aceptable files are up to 24/96 (16/44 for the SD card). OLYMPUS DIGITAL CAMERA More »

Introduction

These must be one of the more controversial loudspeakers from a small British manufacturer to come along in recent caterthuns_pair_011years.  Alacrity Audio’s claims for this small standmount loudspeaker are nothing if not bold!

Take a look at this technical specification ;

Power Handling: 200 W (110 RMS)
Sensitivity: 88 dB
Nominal Impedance: 8 Ohms.
W x H x D: 205 x 415 x 250 mm
Weight: 10kg per cabinet
Frequency Response: sub-sonic to 20,000 Hz +/-3dB
Crossover Frequency: 2.25 khz
Bi-wireable: Yes
Connections: 4mm Gold
Bass Port: Front Reflex
Drivers: LF 17cm Bass Mid / HF 20mm Soft Dome
Optional Extras: Flight Case

Recommended Stand Height: 50 – 60 cm

…. Power handling, sensitivity, crossover point, bass loading, dimensions … blah de blah … frequency response 20KHz down to sub-sonic with +/- 3dB limits … impedance, driver size, connections ….

Whoa! …. Hang on …. you what? — subsonic frequency response?  Have the laws of physics been rescinded or written anew for this speaker?  Interesting indeed.

They aren’t a budget-priced speaker, but at £2,000 a pair they compete with many including ProAc.  I’m not sure the fit & finish is up to ProAc standards, but it is perfectly fine.

No grilles are provided, so proud parents whose little darlings may have cone- and dome-prodding fingers had better be careful! More »

Background

Jade Audio are an American, Minnesota-based company which specialises in audio cables (interconnect and speaker MoonTails 06cables) which use pure gold, or gold-plated conductors.

The Moontails are Jade Audio’s entry level interconnects, but at $550 a stereo pair (RCA) and $800 (XLR), they are perhaps more expensive than many audio fans would consider.  Prices go up to over $4,000 for a 1m stereo pair of RCA interconnects for Jade Audio’s top of the line offering.  Jade Audio are clearly focused on the upper echelons of the hifi price bracket.

The MoonTails are constructed using 99.99% pure gold plated OCC (Ohno Continuous Casting) copper wire; and 99.99% pure silver plated OCC copper wire. These are used in combination to make up both the positive and negative conductors.

These conductors are sleeved in an unbleached cotton dielectric; Jade Audio say that this allows for only 5% of the wire surface to be in contact with the cotton, leaving the remaining 95% in air (the next best dielectric to a vacuum!), and that cotton is second only to air as a good real-world dielectric giving the least energy storage possible.

The appearance is very distinctive, with more than a hint of goldness shining thru the outer sleeving!  They are also surprisingly light, and quite flexible considering their broad diameter. More »

Last year on Hi-Fi Pig Jake raved about Canadian manufacturer Resonessence Labs’ state-of-the-art Invicta DAC, with concero-frontbuilt-in -everything. At some £3000, the Invicta is for those with deep pockets. The Concero, still manufactured in Canada, is the the Invicta’s baby brother, with a price tag of £599, and three modes of operation – USB DAC, S/PDIF DAC and USB to S/PDIF Bridge. It’s a flexible little box of tricks.

The Concero’s main claim to fame is it shares the much-touted ESS Sabre DAC with the Invicta. Will its audio performance live up to standards set by the company’s other device? With the price difference, this is not the ‘scaled down, DAC only version’ without volume pot, SD card function and HDMI out that Jake looked forward to. It’s a much-simplified device.

I used the Concero with my customised MacBook, Tellurium Q Listen pre-amp, bi-amped Tellurium Q Atom power amps and Royd RR3s. I compared it to my M2Tech Young DAC with Super TeddyReg-based PSU.  More »

There are those who argue that valves as used in audio reproduction have ‘no sound’. They are merely devices pure_sound_2a3designed for amplification of current, dependent for their quality entirely on their implementation. We should forget any characterisations of EL34s as sounding sweet, KT88s as warm or punchy, or 300bs as midrange maestros with weaknesses at the frequency extremities. Such sweeping generalisations are entirely wrong, we are told, and expressing them merely a display of ignorance.

And in a purely technical sense, this is true. Given clever design, high enough quality transformers, and a sympathetic choice of speakers for any given product, limitations posed by individual valves’ characteristics can be transcended, stereotypical results avoided, critics’ prejudices confounded, and listeners’ ears delighted.

Sadly, this happens all too rarely. An initial design may be stunning but once production begins, corners are frequently cut to keep component within cost targets, limitations are exposed, and the resulting products all too often fit into stereotypical pigeon-holes. At the same time, a considerable number of designs currently in production are merely rehashings, sometimes inexpertly done, of ancient circuits from the 1950s or even earlier.

Directly heated triodes, while top of the tree in terms of audiophile desirability, are perhaps the biggest sufferers from dubious execution of all the various tube types. I used to own an 845 single ended amp from a prominent continental manufacturer, that despite a hernia-inducing complement of transformers on board needed double digits of negative feedback to hold the circuit together, and made the bass cones in my 97db Tannnoy 15in Monitor Gold GRFs sound like they were made of soggy lettuce (while it wasn’t a great deal better with many other speakers). There are certainly better 845s around than my example above (it didn’t hang about long), but getting the best out of the 845 tube, as with the 211, or indeed the 300b, is an expensive business.

Rod Alexander checks out ‘The Emperor’s New Clothes’

The Technics SL1200 series of turntables have been enjoying something of a renaissance. It’s hard to move in hi-fi Funk SL1210circles without reading or hearing about the great performance that these ‘hidden gems’ (properly modified) are capable of. I’m a former owner – but not an admirer. I’m an ex-owner precisely because I tired of what was, for me, a big but ‘rough and ready’ sound. I’d actually had more than enough of my SL1200 (Mk2) by the time I was 20.

So, like someone who moves on from an XR3 to an RS3. I’m not a huge fan. Very slightly nostalgic maybe (it was OK at the time) but I’m not delusional. As a consequence, I’ve not bothered to familiarise myself with any of the ‘breathed on’ SL1200s available from various sources. In fact, what I’m about to say will have some readers whispering gently to their Technics SL1200s, SP10s or other Japanese direct drive decks, “Don’t listen darling – he’s clearly mad…”  But… I smell a fad.

Quite compact but reassuringly solid and heavy, this 85wpc stereo integrated amplifier is purposeful in appearance. M2 integrated front NBG nbt(1) Eschewing the current Euro-fad for ultra-clean starkness, the Caspian M2 looks like a purposeful high-tech machine, unashamed of its lights, buttons and knobs!  I like it – it has a blunt and honest ‘this is what I am’ attitude that also carries over into its sonic performance.

So, yes, 85WPC – and with 6 line level inputs, and a stereo pre-amp output allowing bi-amping or a separate power M2 Rearamp to be used.  Also, and quite unusually, there is a stereo input to access the power amplifier section directly, bypassing the Caspian M2′s own pre-amp, although this has to be set at the factory.  A single set of stereo loudspeaker output posts is provided.
If you use a turntable for playing vinyl, then you’ll need a separate phonostage.
The current UK retail price is £1699.

The Caspian M2 has remote control of source and volume, plus volume ‘mute’.  Unusually, the mute function only drops the output level by 20dB, which isn’t a massive reduction in sound level.  Personally, I would prefer a full mute with no sound at all when the mute function is selected. More »

Audio Suspension is a new company based in Hove in the south of England and they make just one product at the OLYMPUS DIGITAL CAMERAmoment, the ASU-100 equipment shelf. Now, I’ve always been happy with my turntable on a floor mounted plinth (Ikea table) despite having quite a bouncy floor, but a recent visit by a Hungarian exchange student (a Black Sabbath aficionado) and his somewhat less than delicate stomping across the listening room and the subsequent bouncing of the stylus all over the record that was playing had me reconsidering this state of affairs – It wasn’t really his fault I don’t suppose; he’d not had the benefit of a lifetime of being bellowed at like my two children and long suffering wife have at the merest sign of heavy-footedness in the listening room.

The ASU-100 is composed of a heavy 20mm clear acrylic shelf, 2 polished chrome shelf supports with silicone rubber at wall/support interface and 1.5mm steel wire cables secured by pos-i-lock supports which attach to the wall above the shelf and give the company its name; It does look like a suspension bridge and will support equipment up to 25kg dependent on the fixings you use.

Rod Alexander does some running repairs…

Some hi-fi companies are just instantly likeable. I’m not exactly sure why. An easy-going friendliness helps – the kind ofLDR6_Front attitude that sees staff excited to speak to a real customer, calling to ask for advice about a product. Maybe it’s humour and a general refusal to take themselves too seriously. Tortuga audio definitely fall into that camp, with a website that pulls off the trick of being both informative and light-hearted, along with a head honcho whose default state of mind is “No problem! Can do!”

Founded in 2010 and based in Cape Coral, Florida, Tortuga Audio is the brainchild of

Morten Sissener, an engineer and blues guitarist, who emigrated from Norway to the US as a young boy in the 1950′s. Morten puts his love of engineering down to growing up surrounded by the tools, tinkering and hands-on mechanical genius of his merchant mariner father. Clearly, some of that rubbed off – though given Morten’s love of music and computer technology, setting up a high tech, high end audio company has an air of inevitability about it.

Selling direct from their website, they have just one product – a passive pre-amp, currently available (in single or six input versions, priced at $1195 and $1475 respectively). Tortuga Audio have ambitious plans for their product range though, with an active pre-amp nearing completion and scheduled for release soon. More »

Construction and Styling

These loudspeakers hail from the new range of Tannoy’s prestige series loudspeakers aimed at the higher end of theTurnberry2 market, and employing not just the same technology as their predecessors of old in the use of dual concentric drivers, but also sharing a traditional cabinet design.

It’s probably worth starting with the aesthetics because it’s here that the new Prestige line stand head and shoulders above their more traditional ancestors.  The design has been deliberately kept  ye olde English where the ‘speakers seem if they ought to be fitted with brightly polished tan leather brogues for ‘speaker shoes, or dressed in tweed (hang on…the grill cloth is a little tweedy).  It’s no small surprise that such traditional styling cues have been chosen as the main market seems mainly to be the Far East.  It’s in markets such as Japan and Hong Kong where large floor standing Tannoys are prized possessions as part of the appeal remains the English country gentrification image as well as the traditional and much valued dual concentric loudspeaker design.

The odd thing is that the styling does in fact suit modern minimalist homes as much as it does Chesterfields and oak panelling, so wife acceptance factor (WAF) is likely to be very high.  With the Turnberrys you get a box which stands 95cm tall by 46cm wide and 37cm deep, each box weighing in at a reasonably hefty 30Kgs.  The front edges are crafted from solid European Walnut with left and right edging being twin through-fluted to act as the port vents for the cabinet, which is a neat and aesthetically pleasing design.  The cabinet itself is a hefty and very solid construction of ¾ inch thick plywood/particle board with a European Walnut high quality veneer and it appears to be very well braced and very strong.  They come with a few tubs of Tannoy branded wax polish, which whilst welcome does not make up for the fact that the woodwork from the factory is not all that well finished.

Removing the grill requires the use of a gold plated brass key to unlock the grill panel.  Whilst this may appear gimmicky, it’s actually a good design as there’s no plastic bobbins to snap off and a rather sold locking mechanism which prevents little fingers removing the grills to get to the inviting drivers beneath!

Oracle is a name steeped in hifi history.  A French Canadian company that started in 1979 and made its name with the iconic, aesthetic perfection of its Delphi turntable.  The Delphi continues in production today, and is in its Mk VI guise at around £10,000.

So, what do we have here?

The Paris is the entry-level turntable in the Oracle range.  Although Oracle’s entry level system is costlier than may brands’ top of the range gear!
It is belt drive and the tonearm has to be manually cued.

A choice of four standard high gloss finishes is offered; red, white, black and silver grey. The sample I received was supplied in a beautiful glossy red.  Buyers can however request any colour, for a small additional cost.

The Paris turntable is available as a standard bundle with a Paris tonearm and Paris high output moving coil (mc) phono cartridge.

My wife was very impressed with its appearance and asked how much it cost.  “Over £5,000″, I said.  — “Hmm”, she nodded, unsurprised, “it looks expensive”.  OK, so it passes the perceived value test.

I think it is impossible for me to avoid briefly comparing the Oracle Paris Mk.V turntable package with the budget Pro-Ject Debut Carbon that I recently reviewed for Hifi Pig.
They do look similar. They use basically the same, quite distinctive looking arm.  Superficially, the plinth looks pretty much the same, although comparing the sizes in the respective specs, the Paris is larger, and there is a stylishly sloped-off edge to the right front corner of the Paris’s plinth.

But casual appearances can be deceptive, very much so in this case.  The Oracle Paris has a more sophisticated appearance, as immediately picked up on by my wife.  And in engineering terms it is a far more sophisticated device with an adjustable semi-suspended suspension, substantially upgraded arm and the control electronics and AC motor are the same as used in the top-of-the-line Oracle Delphi MkVI.

Intro

Sliced bread has been with us for decades, yet more and more of us seem to be buying uncut loaves. Similarly, single speed bikes are increasingly de rigueur, despite all manner of technologically advanced, geared equivalents. And so it seems with turntables and all things analogue, with a full-on mini renaissance apparently in full swing.

Some manufacturers’ (Project spring to mind) offer a comprehensive range of decks, all majoring on a minimalist, simplistic appeal, some models incorporating ‘plug and play’ functionality, appealing to a new generation of purchasers. The high end continues to see continued turntable R&D and no shortage of innovation, while there cant be a skip in all of Christendom that hasn’t had been opportunistically eyed up by passers-by eager to chance upon a discarded Garrard or Technics SL-1200 series turntable to have rebuilt to better than original specification and performance.

Rod Alexander gets sceptical about ‘The Tellurium Q effect’

A Mexican stand-off

Securing items for review is usually a straightforward affair. One of the parties (reviewer or manufacturer) approaches the other, they agree upon a review of a particular product, manufacturer supplies product and  info (price, specs, etc) said review takes place, review item returned/review published, manufacturer basks in glory of the review/accuses reviewer of having ears made of cloth . You get the idea. It’s a method that has survived generations.

Unfortunately, Tellurium Q’s Geoff Merrigan didn’t get the memo. He refuses to provide the specifications of Tellurium Q cables, notwithstanding the fact that they are easily uncovered by any fool armed with appropriate equipment, cutting through any attempts at marketing mysticism.

With the cables safely delivered, I had another nibble at him, making it clear that I could uncover the cables measurements in minutes. He still refused to buckle, bullishly stating that the specs are only half the story. What could the ‘other half of the story’ be? Each set of cables is placed in a room where Tellurium Q staff chant in ancient Sanskrit before the cables are packaged and dispatched? The cable termination is carried out by extra-terrestrial beings? The ‘other half of the story’ was obvious to me. Hype.

hORNS Mummy MKii

I’d been waiting for the Mummys for a while and the excitement in the household was palpable. It was kind of like that week before Xmas when you were a child and you knew that the main event was only a matter of a few days a way… but every hour seemed like a lifetime. I’m always like this before any bit of kit arrives for review. Needless to say the usual courier nonsense got in the way and, rather than arriving on the Friday like the tracking details proclaimed, I would have to wait until Monday. Oh, the torment I was longing to give these things a slating as being all style over substance. It was a tough weekend where I busied myself preparing the listening room, moving out old loudspeakers and making room for the arrival of the sarcophagi.

Monday finally arrived and just after lunch there was a knock at the door. Now, for this bit you need to cast your mind back to the Indiana Jones films and imagine a pair of wooden caskets being deposited in Harrison Ford’s sunlit and dusty office. I’d like to say that I’d dressed for the occasion with hat, whip and buckles to swash, but I hadn’t, all I had was my normal attire – yellow socks and a pink cravat (nothing lah-di-dah) and of course, in true action adventure hero style… a crowbar.

The wooden boxes looked for all intents and purposes like I’d taken delivery of two small coffins… the mortal remains of a pair of child pharaohs perhaps. With my trusty crowbar in hand I jimmied the corner of one of the boxes and carefully moved around, slowly releasing the lid from the main body of the box. Laying there in stately grace was the tightly swaddled body of the loudspeaker itself. Carefully upending the coffin and sliding out the loudspeaker was a three man job, these are certainly no light-weights… and so to the cautious removal of the outer layers of the protective wrappings to reveal what lay beneath.

With so many people re-discovering their record collections and many others relying on charity shops to provide them with the “black magic” these days, cleaning LPs has never been more important.  Why bother?  Some schools of thought (prominent audio industry folk) used to proclaim that records should never be cleaned (really!) but the truth is the humble LP needs to be kept clean for several important reasons.  These include the prevention or removal of mould and grease marks from older records, removal of tiny gritty deposits of dirt that will otherwise for-shorten your stylus life, and last but not least because LPs sound far better when clean!

Clean LPs reduce stylus wear, which saves you £££’s long term and the records also sound great when properly cleaned.  If they were undamaged to begin with, they should be near to silent when cleaned and in improving (lowering) noise floor, the dynamic range is restored and the music will sound great.  It’s not enough to just clean the LPs without also storing them in anti-static sleeves after use and always taking care when handling them too.

Of the many different ways to clean records, a few are advisable and a few are not.  Tap water is generally a no-no because it leaves mineral deposits and limescale on the surface when dry. Also, the water, without an anti-surfactant simply cannot get into the very bottom of the grooves to loosen the dirt up so some resort to washing-up liquid.  That in itself isn’t the best of things to do because it contains lots of salt in its make up. So we come to the record cleaning machine, or RCM for short.  Very effective at removing dirt and uses chemicals tailor made for the job, so all good?  Not quite, most RCMs cost more than entire record collections are noisy in use and also take up space.

If you like colourful hifi, then the Pro-Ject Debut Carbon turntable may well be an ideal place to start! It’s available in a range of plinth colours including high gloss yellow, red and the rather startling blue that was delivered to me for review. If your taste doesn’t run to rainbow hues, then high-gloss black, silver or white are also available. Looks matter to many folk, and I think that the range of colours on offer is a fine thing.

So, what do we have here? ….

A relatively low-priced deck which aspires to sound rather good.
It’s belt drive and the tonearm has to be manually cued.

Carbon as a material is rare, to say the least, in a low-priced tonearm. This exotic material is usually reserved for far higher price points where it’s qualities of high stiffness and low internal resonance are much appreciated. But Pro-ject have somehow managed to provide a carbon tonearm in this low priced package. Impressive. More »

Love at first sight

I’m a sucker for the cute and pretty ones. I’ve always been the same. So as soon as I unpacked Ancient Audio’s dinkyStudio Oslo active loudspeakers, I knew I was in trouble. Beautifully finished in deep gloss lipstick red and measuring just 100 x 239 x 210mm (WxHxD) they adopt the ‘narrow frontage/extended depth’ format. For those who would consider the review pair too, errr… ‘tarty’ they are also available in white or black gloss as well as ebony and rosewood veneers.

Hailing from Poland (despite the Norwegian moniker) the Studio Oslo is described as a ‘nearfield powered monitor speaker’. Given the connectivity on offer, it’s hard to argue. With balanced XLR inputs, in addition to 2 pairs of RCA phono sockets (for high and low level signals) along with volume and – wait for it, tone controls, they certainly tick the studio monitor checklist.

With an eye toward their likely placement on desks, from the side they have a parallelogram profile, ensuring that the single full-range driver, sourced from Dayton and featuring an anodised aluminium cone, fires slightly upward, toward the listener.

Connections and power amplification reside in one of the speakers, along with an analogue sound processor, precisely set to optimise the performance of the drivers by compensating for phase shift and amplitude variations across the driver’s frequency range. An umbilical provides signal to the left speaker. Onboard amplification is based around the Philips TDA8566Q IC, providing 30 watts of power. Ancient Audio state that they have biased it well into class AB, but in use, the rear-mounted heatsink barely rose above room temperature.

The units come complete with a simple laptop type power supply, though Ancient Audio state that any laptop power supply with an output of 17 – 19 volts DC will do the job. Ancient can also supply an adaptor that allows the speakers to be used with car or leisure type batteries. More »

When I was asked to review this little headphone amp I was a little hesitant as to what to expect, but I was assured by the UK distributor that it was a goodie.

Let’s get the technical spec out of the way first. This is headphone amplifier and USB DAC in one compact little unit with a power output rated at a healthy 1 Watt per channel in Class A. It has a switch on the back to switch between 32, 120 and 300 Ohm headphones, two stereo line inputs, a stereo minijack input, a USB input and a stereo line output. It can also be used as a preamplifier…more of which later.

In the packaging you get a small instruction manual, a pair of white gloves, the amp and its hefty separate power supply. Valves fitted are 1x6N2X1, 1 x 61X1 and 1x 12AX7X1 and the whole caboodle weighs in at 5Kg.

It’s an attractive little unit being matt black aluminium with the valves being kept from harm behind individual transparent ‘cages’. On the front of the DARED is a large input selector knob where you can switch between Line 1, Line 2, Aux and USB, a volume control dial, the headphone output socket and a round, illuminated VU meter which lends the amplifier a somewhat retro feel. It’s a nice looking bit of kit measuring 180 x 220 x 150mm (LWH).

You may not have heard of DARED but the Shenzhen Danyigao Audio Equipment Limited was founded in 1995 with the “sole purpose of designing and manufacturing vacuum tube audio equipment” and DARED is the company’s registered trading name. The name DARED derives from the Chinese pronunciation of ‘Dan yi gao’ which means “high-end tube amplifier and artistry” – In English the company use “Daring, Artistic, Reliable, Elegant and Definitive” as their mantra. DARED kit is designed and manufactured in Shenzen, China, the company say that all their products are thoroughly tested electronically and by ear before leaving the manufacturing plant and that every unit is properly “run in”. The units all bear the CE mark and letters of authentication can be found on the company’s website. There is a wide range of amplifiers in the company’s portfolio with the T300P monoblocs being their flagship product – a pair of these amplifiers boasts no less than 16 x 300B valves and weigh in at 95Kg for the two!

For the purposes of this review I’ll be using the DARED with a Wilson Benesch Circle turntable fitted with a modified Rega RB250 arm with an Audio Technica AT33EV moving coil cartridge, through an Electrocompaniet ECP 1 phono stage. For Redbook CD I’ll be using the Unison Research CD Primo and I’ll be using the Hi Sound Audio Studio digital audio player into the auxiliary input to test that out too. The USB DAC input will be fed by a netbook computer with FLAC files. Headphones will be primarily Grado 325i. More »

These are the big brothers to the standmount LFT-16a speakers recently reviewed in Hifi Pig. At just over 5 foot (1.6m) tall and weighing in at a fairly hefty 41Kg, these will be difficult to hide away in the corner or to sneak past your Significant Other!

Once again they are quasi-ribbon hybrids, but with the LFT-8b the quasi-ribbon array is much larger and covers a larger proportion of the frequency spectrum, and a larger woofer cone and enclosure is used to handle the bass. As the listening sessions showed, though, it’s not just bigger helpings of the same sonic flavour but a rather different style of presentation.

Technology Background – Different ways to re-produce the music

To recap on the LFT-16a review –
(feel free to skip this section and the next if the previous review is still fresh in your mind!)

The most usual loudspeaker technology is based around a cone or dome made out of paper, plastic or metal with a coil of electrically conductive wire (the voice coil) attached, and with an adjacent magnet structure. An electrical signal is applied to the voice coil, this interacts with the magnetic field and the cone or dome moves in time with the signal variations. Make the signal variations the music signal, and music is the resulting sound created by the air movement.  The problem here is to make the cone or dome stiff enough that it precisely follows the input electrical signal. The cone/dome material flexes; it has to, nothing is perfectly rigid. Strengthen the material to make it stiffer and you will most likely increase the mass, which reduces the responsiveness of the system and so reduces the resolution of the sound. Material and magnet type can be improved, generally at a cost and with the usual law of diminishing returns.

Eminent Technology takes a different approach, at least as far as the midrange and treble parts of the audio spectrum are concerned. They use “magnetic planar” drive units for that. An electrically conductive aluminium track is etched onto a light Mylar film and is placed between an array of strong magnets. The audio signal is passed through the aluminium track, and the magnetic field so produced interacts with the magnets and causes the Mylar film to vibrate, producing the sound.

It’s the same kind of principle as electrostatic and ribbon speakers; a thin, lightweight diaphragm moving the air. The advantages are similar, too …. Low colouration, as little energy can be stored and released later. No need for boxy cabinetry, so another source of colouration is removed. High diaphragm ‘acceleration’ due to the low mass of the diaphragm, so resolution can be very high. Excellent high frequency extension, once again due to the low mass of the moving material. There is a lot going for the approach!

The main disadvantage is that the excursion limit of the diaphragm is more restricted than for a conventional cone driver, in order to keep the driver within the linear region of the magnetic field, so less air is moved for the same driver area. This results in lower sound pressure levels and restricted bass extension. The way around this is to increase the diaphragm area – this of course increases the size of the speaker (full-range electrostatic and ribbon speakers can be very large!) and also increases the cost.

Well I never thought I’d be writing a review about an app for the iPod Touch on Hifi Pig, but when I saw this little bit of kit for just 99cents I thought it would be worth a bash.

The Speaker Angle app is made by a company called Audio Apps, headed up by a guy called Howard Massey. The company was set up only a few months ago to create a line of unique and innovative little mobile apps geared towards the home studio and pro-audio markets. Speaker Angle is the company’s first release and it’s been developed with the help of the people at Genelec.

Speaker Angle is a little tool for accurately measuring the angle of toe-in of your speakers and will work for both 2 channel and surround sound set ups and as such I thought it would be useful in the hifi room.

Now, I don’t actually own an iPod or even know how to get these things called apps onto the beast and so I commandeered youngest son, the resident apple fanboy and his little box of tricks. After about a minute or so the app is on the iPod and we’re ready to go. After a bit of pointing the thing at my main loudspeakers and whining about how silly iPods are and how useless the app is I thought I ought to read the instructions. More »
