Has Icon Audio founder David Shaw designed the ultimate push-pull triode amplifier? Asks the latest press release Icon Audio MB81from this well known British manufacturer.

For much of the last year, Icon Audio founder David Shaw has, in his own words, been building his own birthday present.  After discovering a quantity of ‘new old stock’ Russian GU81 transmitter valves, Shaw began to work on a prototype amplifier that would achieve a long-held personal goal: to effectively drive any modern low-efficiency high-end speaker to realistic levels.

Shaw has long been a fan of triode operation, being the purest form of valve circuit. But triodes have a downside: limited power output.  After many months of designing and listening, Shaw has produced what is, in essence, the final pre-production prototype of the Icon Audio MB81: a triode monoblock which can deliver 200 watts RMS into even the most demanding of loads.

At 260mm tall, 100mm in diameter and weighing 1kg each, the GU81 is a truly majestic valve. Although the GU81 still in production, Shaw has used ‘new old stock’ valves in the MB81, hand-chosen for their combination of fine resolution, enthralling musicality and immense power.  Always keen to break boundaries and set trends, Icon Audio believe the MB81 to be the world’s first ever push-pull GU81 amplifier.

These massive amps are around 50% bigger than the current Icon flagship MB845MkIIm and weigh around 100kg per pair.

While the MB81 was developed as a personal gift for Shaw himself, he plans to produce a limited number for sale, with an estimated price of £12,500 per pair.

The MB81 will be demonstrated at this week’s National Audio Show at Whittlebury Hall.  Visitors will be the first to witness the life-like scale of the stunning new prototypes from Leicester-based Icon Audio.

  • Pure Class A triode front end.
  • Triode GU81 push-pull output stage.
  • The four GU81s can be user-calibrated using Icon Audio’s built-in ‘Easy Bias’ meter.
  • All hand wired with silver plated pure copper PTFE audio cable to optimise sound and reliability.
  • Low distortion quaternary wound output transformers, potted to reduce noise.

Brought to the UK by Absolute Sounds ­­the oBravo HAMT-1 is a “luxurious pair of high-end headphones with a unique oBravotwo-way driver configuration delivering game-changing sound” says the press release we’ve just received at Hifi Pig.

The oBravo are the world’s first coaxial two-way headphones featuring AMT driver technology which is unique and fully patented.

Each earpiece contains two separate drivers sharing a common axis: a 40mm AMT tweeter and a dynamic Neodymium bass/mid driver, radiating sound from the same point. This driver configuration is said to deliver an “exceptionally rich, detailed and immersive listening experience, with astonishing clarity in the midrange and effortless extension at frequency extremes”.

The headphones’ outer construction combines aluminium, wood and hand-stitched leather for distinguished styling and comfort.

About AMT Drivers

An AMT (Air Motion Transformer) loudspeaker driver moves air using a folded diaphragm, structured around a series of aluminium struts within a high-intensity magnetic field. When signal current passes through the struts, the diaphragm pushes back and forth from itself in a physical motion similar to that of an accordion when pushed and pulled to pump air though the reed chambers, albeit over a far smaller motion range. The result is a dipole driver with an extraordinarily rapid response rate, enabled by the extremely low mass of the diaphragm and the much smaller distance it travels on each ‘swing’ compared to a dynamic driver with a traditional cone.

The discernible motion of each diaphragm flexure is very small, but because of the folded structure, more air is moved than would be by a conventional cone of the same plotted surface area. As a matter of surface comparison, a standard 25mm AMT strip has a functional driver area comparable to an 200mm circular dynamic cone. The folded driver design, combined with the small motion range, means the AMT acts like a point source version of a larger driver, resulting in lower distortion. As a result of its motion pattern, the AMT ‘spits’ the air out in a way similar to the action of shooting a watermelon seed from your hand by squeezing it between thumb and forefinger. The speed of the air as it leaves the diaphragm is approximately five times faster than the speed of the actual driver structure, hence the name, Air Motion Transformer. AMT drivers are rare to find in full-size loudspeakers, and rarer still in headphones.

The oBravo HAMT-1 is priced at £1,499 inc. VAT

Following the recent announcement that KEF was to expand the Blade speaker range with the introduction of the KEF Blade Two, the new model is set to be showcased at this year’s National Audio Show – the first demonstration anywhere in the UK.

Available in five specially selected finishes chosen to complement Blade’s sculptural contours, Blade kef_blade_twoTwo is both smaller in height and depth than Blade. Its size has been configured to retain the integrity of the iconic visual design and the acoustic prowess, yet on a practical level provides greater ease of positioning and placement within smaller environments where space is at a premium and where Blade’s bass extension would be superfluous.

At the heart of KEF Blade Two is the inspired Single Apparent Source technology. The Single Apparent Source technology is an extension of the latest, fully pistonic KEF Uni-Q® MF/HF array, which brings the bass drivers into the picture for the first time.

Four 6.5” (165mm), newly developed bass drivers deliver the KEF Blade’s low frequency response. The engineering principle behind their configuration is simple – let the forces of each moving cone cancel each other out by arranging them in opposed, symmetrical pairs – but its effective implementation is fraught with engineering obstacles. The force produced by the bass drivers is so strong that the massive rear magnets have had to be bonded directly to each other to obtain the full benefit of this technology. They are side firing so their acoustic centre coincides with those of the all new, latest generation Uni-Q midrange driver and tweeter – this is the Single Apparent Source technology. The result means that the entire frequency range is radiated from one point in space. “It is impossible to determine where one driver stops working and the next begins, meaning that the resulting sound-field is astonishingly convincing”.

All this technology is housed within a rigid and heavy cabinet made from ultra-high density polyurethane. The parabolic curvature of the enclosure increases cabinet rigidity even further and the drivers are fully decoupled, meaning that sound is only generated from driver movement and not from the cabinet.

The new X3 from Kudos uses the same tweeter as its ‘baby brother’ the X2, but marries it with a Kudos X3 closeup.jpegnew 18cm main driver. The main driver’s cone is made from a mixture of paper and reed fibres, which Kudos say “combines inherent stiffness and natural damping with light weight and improves transient and dynamic response, as well as overall clarity”. The driver has a copper-clad aluminium voice coil and copper shorting ring which they say will “further enhance transients and dynamics and reduce distortion, increasing transparency”.

Both drive units are manufactured exclusively for Kudos by Norwegian specialists SEAS and specifically designed for the Kudos loudspeaker range.

Integration between the two drive units allows the use of a low order crossover and all internal wiring features The Chord Company’s Sarsen loudspeaker cable.

The X3’s cabinet is constructed from 18mm high density MDF with the reflex port situated on the bottom of the cabinet so that the plinth then provides a fixed boundary gap for the port to work optimally, as well as providing additional stability.

“The X3 was purposely created in response to customer demand for a slightly larger, more dynamic and even more exciting version of the X2 miniature floorstander”, says Kudos’ designer Derek Gilligan. “Using ideas first implemented in our flagship ‘Titan’ and ‘Super’ models, we developed the X3 to be easy to drive and to position within a room, and to bring out the best in a wide variety of music – delivering the energy, exuberance and life within a piece of music whatever its genre”.

Russ Andrews Accessories has introduced the X4 Block and X6 Block mains extensions with built X414s1_webin Silencer technology, complementing their X2 Block and incorporating the company’s UltraSocket mains sockets and aiming to provide a secure and quiet mains supply connection for up to four or six pieces of equipment respectively.

The new blocks are anufactured from impact and fire resistant ABS plastic and internally wired with Kimber TCX mains cabling. Ultra Sockets with DCT treated nickel-plated high pressure contacts, originally specified for the company’s top of the range Ultra PurifierBlock, are fitted throughout the X Block.

Each block is fitted with the Russ Andrews SuperClamp surge protection technology and Silencer mains filter.

A 10A IEC input socket provides flexibility for the user to specify the type and length of mains cable to connect the X Block to the wall socket.

Chairman of the company, Russ Andrews, says, “When we launched the X2 Block a few years ago the purpose was to provide a high quality extension and connection for people who only have a simple hi-fi system with two components, for example an amplifier and CD player and who didn’t need larger blocks. Such was the reaction to the improvements in sound quality that we were repeatedly asked for ‘more of the same please’.” He continues, “By adding the new X4 and X6 Blocks to the range we have brought the high performance benefits of the X2 Block to a much wider audience, while at the same time maintaining an attractive price.”

Prices
X2 Block with Silencer £169
NEW X4 Block with Silencer £259
NEW X6 Block with Silencer £349

The new wallmount speaker from Wilson, the Alida, incorporates the same anti-jitter crossover Alida Press Release Page 4technology that underlies the full-size Wilson loudspeakers. “The greatest challenge for any wall-mount loudspeaker is accounting for the deleterious interaction with the wall and ceiling, as well as degradation caused by the mount itself. Alida minimizes wall/ceiling resonant interactions through thoroughly re-engineered mounting system” says the company’s press release. The Alida is mounted to its bracket via a new individually machined, aircraft-grade aluminum mechanism which Wilson say will reduce wall-born interactions and resonances.

Where the outgoing Wilson Wallmount could be rotated up to 10 degrees, Alida’s new mount provides up to 30 degrees of rotation.

For those clients upgrading from the Wallmount Series 2 to the Alida, Wilson has made the task of swapping the two loudspeakers relatively straightforward by providing compatible mount locations on the X-material wall bracket. Simply remove the old bracket and replace it with the Alida bracket. For an additional fee, Wilson will paint the X-material bracket to match the wall or the Alida itself.
Using materials technology first developed for the Alexandria XLF and the Sasha W/P, Wilson have been able to “reduce the resonant signature of the Alida enclosure to vanishing levels”. A rear-wave diffuser, similar to the technology found in Wilson’s larger speakers, Is employed to “reduce time-domain distortion inside the cabinet”.

The new Wilson CST tweeter, first found a home in the Alexandria XLF is used In the Alida and uses a new silk dome design. This version of the CST features a bespoke rear-wave chamber, designed specifically for the Alida platform. Additionally, Wilson will offer a custom version with the its modified titanium dome tweeter for those customers replacing the outgoing Surround, who still use front speakers with this tweeter.

The grill frames on the Alida are built entirely from its proprietary composite X-Material which Wilson say converts unwanted vibrations into heat. Sponsorship button
