Back in January Hifi Pig ran a news item about a new Bitish company called Computer Audio Design and their debut CADproduct the CAD 1543 DAC.

The latest news to come from the Computer Audio Design offices is that the company’s DAC has been awarded “Best Sounding Hifi Room” at Britain’s biggest audio and home cinema show, Sound and Vision 2013 (The Bristol Show)

Computer Audio Design’s new CAD 1543 DAC saw off competition from 188 exhibitors at a packed show, with designer Scott Berry clearly wowing the judges with the sonic performance of this USB-only DAC. Vice-chairman of The Clarity Alliance, who gave the award, Simon Byles, said: “It is important that the hard work and effort put in by the many companies which exhibit at the premier UK hi-fi show is recognised and rewarded.”

A hearty “Well done” from all at the Hifi Pig sty!

Simplicity is the keyword for Bergmann Audio and when Hifi Pig received news of their Magne tonearm we couldn’t help but share it with our readers.

The Magne tonearm is a linear tracking airbearing design and so something a little out of the ordinary where tonearm Magne separate Tonearm_page1_image1design is concerned. The moving part of the tonearm simply floats on a thin cushion of air, and is led only by the stylus tip and the record groove. The arm is manufactured with as few parts as possible and from solid materials which Bergmann say avoids unintended resonances and maintains optimum stability

The Magne tonearm (the moving part) is designed and assembled as one, non-adjustable unit, which consists of an aluminium sliding pipe, carbon armtube (double tube with damping) and the head shell. The head shell is fixed completely parallel to the sliding pipe, for a perfect azimuth. If azimuth adjustment is required, it can be done by using a spacer. The counter weight is decoupled from the armtube.

A Linear tracking tonearm tracks the record as it was originally cut/pressed which means there should be no tracking error and the benefit is said to be a distortion free and relaxed reproduction, even at complex passages. Another claimed advantage of the airbearing is the tonearm’s immunity to acoustic feedback, as it has no mechanical contact  to the turntable other than through the stylus tip and the tonearm wire.

PMC unveiled the SE version of the BB5 at Sound & Vision, The Bristol Show. news_se_bb5The BB5 SE is a domestic version of the company’s world leading studio monitor, the BB5-Active.

The BB5 SE is the flagship of the new SE series of loudspeakers which also includes the other large three-way models, the IB2 and MB2, and combines PMC’s renowned build quality with  Rose and Macassar veneers to ensure the loudspeakers will not look out of place in any domestic setting. Internally, the cabinets have been redesigned to generate a lower cabinet resonance for further “reduced cabinet talk, a purer musical signal and better handling of bass transients”. “The SE series possesses improved clarity in the midrange, through the use of an innovative profiled dispersion flange for the renowned PMC 75 midrange driver; which, in the case of the BB5 SE, is handed to eradicate baffle diffraction to further improve the imaging”.

“Special attention has also been given to the detailing on the terminal panel and the new tactile Nextel™ texture provides a luxurious finish on the drive units. Custom designed stands, in a matching veneer and fitted with large spun precision spikes, complete the aesthetic and provide a firm foundation for the speakers”.

Peter Thomas says of the new models, “Our i series has been a fantastic success all across the world, building upon our studio heritage to bring accurate music reproduction to music lovers in the home. Now, with the SE editions, we have improved the performance of these models even further so that the most discerning of audiophiles can enter right into the heart of their music and hear it sounding just like it did in the studio.” He continues, “And with the beautiful new veneers we have chosen, the speakers look every bit as stunning as they sound.”

Record Store Day was founded in 2007 as a celebration of the unique culture surrounding over 700 independently Printowned record stores in the USA, and hundreds of similar stores internationally. This year the event takes place on April 20th.
This is the one day that all of the independently owned record stores come together with artists to celebrate the art of music. Special vinyl and CD releases and various promotional products are made exclusively for the day and hundreds of artists across the globe make special appearances and performances. Festivities include performances, cook-outs, body painting, meet & greets with artists, parades, djs spinning records and on and on.

To show Hifi Pig’s continued support for Record Store Day and to demonstrate our solidarity with the bricks and mortar independent record stores across the world that continue to feed our desire for music, we are announcing the closure of our online record store with immediate effect. (If you have already placed an order it will still be honoured). We hope that you will see this as a clarion call to get out there and support your local record stores, not just on Record Store Day itself, but throughout the year. Furthermore, we have now added a section to the Hifi Pig “Directory” specifically dedicated to independent record stores throughout the world. If you are a record store you can add your details for free in our online directory of record shops.

For many, record stores will have been an intrinsic part of growing up. Many readers will remember quite specifically the first time they went into a record store, flicking through the vinyl, CDs (and even tapes for us older ones), buying that first piece of music and then getting it home and sticking it on the hifi. Record stores are not simply retail outlets, they are places where memories were made and as such they deserve our and your support.

Hifi Pig is delighted to announce a new member of the review team in the guise of Danny Worth. Danny has a wealth danny lightof experience with lots of different hifi equipment after many years of experimentation and auditioning and we are very pleased to have his knowledge and experience on the team.

Danny’s passion for high end audio is very much in the here and now and he’s something of an aficionado of all things streaming and computer audio – as such he will concentrate on reviewing items that are very much in this vein. That said, he also has a bit of a soft spot for valve amplification and comments “To compliment the convenience of digital recordings I love the sound of valves and to feel the balance that can be achieved between a digital front end and a valve amplifier in conveying a wonderful and realistic insight into the music”.  He’s also something of a cable fanatic and so watch out for some interesting audio cable reviews in the very near future.

Any new release featuring Mike Patton is sure to pique the interest of many a musical pundit, and interests were more than piqued when the band described this album as being like “like a heavy version of the Beach Boys” prior to its release.  I for one was intrigued about the concept, despite Tomahawk being regarded as somewhat lower in the pecking order of the Patton canon by fans and industry types alike.  Mr Bungle, Fantomas and of course Faith No More seem to be the Patton projects du jour.  However, Tomahawk is more than just Mike.  Joining him are John Stanier (Helmet, The Mark of Cain) on drums, Duane Denison (The Jesus Lizard) on guitar and long time Patton collaborator Trevor Dunn on bass.  Oddfellows is their fourth album, following on from the underrated and visionary reworking of native American songs that was Anonymous in 2007.

Earlier today Hifi Pig ran a breaking news item about the new Cyrus 30th Anniversary Edition system and we have now Cyrus full thismanaged to snoofle out further information about the system from Cyrus as well as a photograph.

The new system will comprise of the following individual items:


For the Anniversary Series version of the CD XT SE2, Cyrus has made a number of changes including the addition of new AC and DC power filtering, plus additional motor control stage filtering elements.

Stream X2

The Stream X2 represents the top model in the company’s range and is a music streamer and internet radio source. To improve performance over the original, Cyrus has added new power supply power filtering and made improvements to the chassis to minimise resonance and the unwanted effects of microphony.


The DAC XP+ with its built-in preamp has seen an extensive improvement programme in the Anniversary Series. Its DAC chips have been upgraded to 32-bit resolution running in fully balanced operation and there have been numerous changes to the power supply including: upgraded power transformers; extensive new power filtering and improved smoothing on the DAC supply; new ‘short path’ analogue input switching stages plus an updated XLR output design, providing a purer balanced output circuit.

Mono X 300

The Mono X 300 is Cyrus’s most powerful amplifier to date and with its zero-feedback design it gives 300 watts. The Anniversary Series updates include a replacement input buffer op-amp with a higher slew rate and higher gain bandwidth, for a “smoother high-frequency response” plus additional power filtering to reduce electromagnetic interference across all supply voltages.


The PSX-R is said to provide an extremely smooth and stable DC feed, “the PSX-R enables the DAC XP+ and CD XT SE2 transport to reach their full potential” and in this Anniversary guise, includes new AC and DC power filtering which reduces noise across output supply voltages.

Hark II rack

The Hark II rack is a stylish addition to any Cyrus system and is included within the Anniversary Series package. The contemporary vertical system rack features adjustable shelving and is purpose-made for Cyrus components. The rack features an aluminium extruded side blade, which hides wiring, while also providing a power distribution storage compartment. The Hark II rack is expandable, with the system capable of holding up to a total of eight units.

Schiit Audio announce the production of the Asgard 2 headphone amplifier. Asgard 2 is a complete redefinition of the asgard2company’s Asgard headphone amplifier, adding both a higher-performance gain stage based on their flagship Mjolnir amp, as well as features such as selectable gain and preamp outs.

“With these changes, Asgard 2 becomes a complete control center for desktop audio,” said Jason Stoddard, Schiit’s Co-Founder. “It provides switched preamp outputs for use with powered monitors, and exceptional flexibility to power headphones from sensitive IEMs to power-hungry orthodynamics.”

IEMs are a special focus of Asgard 2. At the low gain setting of 1.5x, the noise floor is said to be exceptionally low and the Alps Blue Velvet pot provides a “very fine range of control, with excellent channel matching”.

Asgard 2 offers a high gain setting of 6x, and can provide up to 1W of power into 32 or 50 ohms, making it suitable for many power-hungry planar-magnetic, or orthodynamic headphones. With output voltage up to 30V p-p, it also pairs  with high-impedance, 300 and 600 ohm headphones.

Like all Schiit products, Asgard 2 is made in the USA.

Von Schweikert Audio announce the VR-100XS speaker system.  All aspects of its design have VonSbeen approached with the goal of an “acoustically holographic listening experience of a live musical event”.  To achieve this, the company have engineered an all-new Noise Reduction cabinet construction based on their Triple-Wall constrained layer patent, a matched driver array using the same magnesium diaphragm material from woofer to mid to tweeter for coherent timbre response, transient-response “speed” matching of the driver array using proprietary servo-controlled filter circuits instead of a “crossover,” and room-correcting subwoofer design that eliminates the standing wave phenomena through the entire room.

The speaker drivers are implemented as a vertical array as in the company’s VR11-MkII.  As recording microphones are “point sources” Von Schweikert have designed a Point Source concentric driver array to  recreate a “holographic experience”.  The initial source of the focal point is the centered tweeter, with concentric arrays of midrange and woofer drivers.  On the rear of the tower is a two-way Ambience Retrieval System that will complete an omni-directional spherical-wave radiation pattern.

In each VR-100XS tower, the four 7″ woofers and two 5″ midrange drivers are custom-designed, ultra high speed, non-resonant magnesium-coned units, damped with a layer of ceramic oxide.  The cone material is extremely light, rigid, and tonally accurate and the company says “surpasses any electrostatic driver for transparency”.

The newly designed ribbon tweeter, placed centrally in the array, has both ultra wide frequency response and wide dispersion due to a proprietary wave-guide.  Transient response matching of the drive units, from the 15” magnesium-coned subwoofers up to the 2”  magnesium foil/Teflon ribbon super tweeters is controlled by a proprietary circuit with “servo control” using the drivers’ back-emf for sampling of the signal versus driver response “speed” in actual “real” time.  A feed forward circuit was designed to electrically damp the driver behavior to match each other driver as closely as possible.

The new one-piece cabinet is massively constructed and each tower weighs over 460 pounds. The Main Towers are 1ft wide x 6ft tall and are available in many high quality automotive finishes.

The external sub-woofers, the “XS” of the system, are also an all new VSA engineering solution.  They are designed to be placed near the rear of the listening area and are aimed at the main towers. Von Schweikert’s new patent pending technology will “eliminate room response anomalies when integrated with the already outstanding bass performance of the VR-100XS towers”.  The XS subwoofer amplifiers have Time Delay controls to adjust the response for the room dimensions and can be adjusted to compensate for standing wave modes in any room, no matter the size.  “The elimination of standing bass waves in the room is not achieved by equalization in the subwoofer amplifier, but is achieved by acoustical cancellation of Eigentones throughout the room, without any digital implementation of any sort”.

Bass extends down to 10 Hz and has transient response speed and clarity that equals the response accuracy of the loudspeaker’s midrange drivers. The supplied subwoofer amplifier is designed and built in the USA; it supplies over 1,000-watts r.m.s. into each of the four voice coils of the Super Duty High-Speed Infrasonic Subwoofer driver.  With a 60 pound  motor and four 5” voice coils configured in Push-Pull operation, the 15” magnesium cone with a 3” total excursion potential has the” lowest distortion and quickest transient response speed of any subwoofer on the market”.  A Signal Sensing Cable made by Delphi Aerospace is supplied to connect the Main Towers to the Sensing Inputs of the XS subwoofers – the subwoofer signal is not sent from the preamplifier.  In order for the subwoofer to “follow” the main woofers, Von Schweikert have implemented a ‘servo-controlled’ feedback loop from the main woofer’s back-emf (electro motive force) output to “tell” the 15” woofer where to go, in terms of speed and tonal quality.

The rear-facing implementation of the VSA “GAIN” Ambience Retrieval System “breaks new ground”, as Von Schweikert have engineered a solution to recreate the desired dispersion pattern of an omni-directional speaker system. This required a dipole implementation of a rear wave that combines with the front wave to generate a “side beam” of sound to enhance the “openness” of a live performance.  Using both a 1.25” dome midrange and an additional 3” ribbon super tweeter, the 2-way design operates from 1,5kHz to 100kHz.  “The 1,5kHz frequency was chosen by examining the polar response of the front driver array’s response at 90-degrees off axis”.  When both the front and rear driver arrays are measured, the speaker behaves as a quasi-omni speaker, similar to a cardiod pattern as in recording microphones.  This new “HGAIN” technology couples with the front drivers, completing the you-are-there holographic experience.

Relevant specifications at time of publication are: $145,000 for the 4pc system consisting of two Main Towers and two XS subwoofers with 15” drivers and 1,000-watt amplifiers.  Main tower is 6 ft tall x 1ft wide x 30” deep with a weight of 468 lbs uncrated.  The XS subs are 176 lbs @ 24” x24” x 24”.  System sensitivity is 90dB, impedance is 4-ohms, recommended power rating is 50 watts to 1,000-watts, frequency range is 10Hz to 100kHz.  Main Towers have Autoformer Level Attenuators for front Tweeter and Rear Ambience.
