NASWith great appreciation to Justin Anon (User211) I am delighted to be able to present a mostly photograph show report (I will add detail and discuss items of particular interest) of the National Audio Show (taking place as I write), held once again at Whittelbury Hall, in the beautiful Northhamptonshire countryside in England.

Its been a frustration of mine that in recent years life has kept me away from NAS, this year I had hoped to attend but once again it didn’t happen and based on the photos Justin took that looks to have been a real shame as there are some very interesting items in them.

Unlike previous NAS reports this one very much reflects Justin’s particular interests and as such is not a total show report.

Here is the NAS 2015 online Show Guide

So without further ado and in no particular order here are the highlights of NAS 2015




Inspire HiFi – Ground Floor Monza Suite  


Inspire Audio had their usual varied selection of their own original turntable designs on show plus their reworked Lenco (The Enigma) and the Monarch direct drive (which uses a Technics 1200 drive unit in conjunction with original Inspire parts, platter, bearing, PSU, control interface, chassis, and plinth) design. Also on display were a number of user installable turntable upgrades.



The New Black Magic Si entry level turntable £600 (with Rega 202 tonearm, sans cartridge)



New Inspire Elevation turntable £1550 (with Rega 202 tonearm/sans cartridge)

Inspire say this about it – ” The Elevation turntable is an extremely hi mass turntable that oozes class with its performance, looks and quality.

Together with its very high mass and careful use of materials such as the dense and inert platter. The sound stage, deep bass and precision timing combine to give the listener an altogether exhilarating musical experience.

Origin Live – First Floor Room 103


NAS 2015 saw the first showing of Origin Lives impressive looking new statement turntable The Voyager £12900 (excluding arm)


Origin Live say this about the Voyager….

“The Voyager turntable is the culmination of over 25 years spent researching the art of turntable design. It’s awsome performance derives from many tried and tested techniques along with very innovative ideas. This is nothing less than you would expect from our track record of 17 Awards won through long experience in the control of micro-vibration.

The Voyager is also available in an “S” version where no expense is spared. Higher quality materials and expensive machining is necessitated along with numerous “under the bonnet” detail improvements. A 2nd drive motor is also included in the S-version. Every possible care has been taken with the usual conscientiousness of Origin Live, to produce an utterly exceptional performer.

Great attention has been devoted to the design of the platter and bearing assembly. The concept is, to transmit energy instantaneously out of the record, and at the same time prevent vibration from the motor, the bearing, and the environment, entering the record. This sounds simple but is very hard to achieve in practice.

The Voyager platter uses intricate (and little understood) mechanisms to create the equivalent of mechanical diodes. For non electrical readers, a diode allows electrical energy to flow only forwards but not backwards. Standard heavyweight platters are abysmal in achiving this requirement as they tend to reflect vibration in the record (produced by the cartridge), straight back into the record.  Felt mats only tend to transmit certain frequencies which cause timing problems and other issues.

The Voyager uses a multi part platter designed to transmit energy at all frequencies without the reflection problems encountered by many platter designs. The energy is controlled by a series of shock absorption mechanisms created from our long experience in controlling micro shock waves. Key components are made from well specified alloys to achieve highest energy transmission speed and low “ringing” effects. Material composition, profiling and the right damping methods are critical to accomplish this.”turntable-voyaver-front-2True expertise is the ability to know which details make all the difference. Some High End decks invest enormous sums in fancifull, ideas that don’t make a musicaly coherent product. You will notice that the Voyager has many seemingly insignificant details. For example, lightening hole profiles and part shapes are all carefully derived from experience of structural analysis – vital for the correct manangement of micro-vibration. This is not the brute force approach adopted by many spectacular decks where energy reflection seems to produce a lack musicality and subtle timing in the micro dynamics.

turntable-voyager-angle-frontThe Bearing in the standard Voyager possesses extremely low levels of friction and vibration. Features include, extreme precision, large diameters for rigidity, special oil and high mass.

The Voyager Motor is renowned for it’s reliability and smooth rotation.
Drive belt consists of a low stretch, high grip material which is now widely recognised (in the form of our “upgrade belt”) as a significant advance over normal belts, threads, tapes etc.

Plinth is constructed from high grade alloy and carefully damped to reduce ringing effects.

Up to 3 off, 9″ to 12 inch tonearms can be mounted at the same time. Armboards are easily changed and adjusted.”

Long Dog Audio – Ground Floor Room S10


Long Dog Audio were running an interesting system using Passlabs XA100.5 mono amplifiers, a new to me turntable from Reed, the Muse C, and the Long Dog Audio designed Music First Audio Reference Phono stage, Classic Step Up, and the Baby Reference Pre.


Music First say this about the Reference Phono Stage £ 9840 –

“The Music First Reference Phono Amplifier is an all valve moving magnet phone stage, employing innovative (possibly unique) circuit design, careful component selection and LCR RIAA equalisation.

Whilst on paper, the requirements for a phono amplifier are simple, in practice, they are far from it.

We start with a signal from the cartridge or step up transformer of only 1mv, then apply enough gain to convert that to a line level signal while at the same time applying a accurate RIAA equalisation curve. while at the same time providing a low impedance drive to the following system. Firstly, the 1mv signal. If we want to aim for the best signal to noise ratio, we need to look at at least 80dB S/N here. For a 1mv signal, then that means the noise needs to be below 100nv (0.0000001v). But it goes further that that, the RIAA curve means that the low frequencies will be 20dB (10 times) lower. That means we are looking for a input stage that can give us a 100dB S/N ratio, we are down to 10nV. But to prevent surface noise, clicks and pops from affecting the sound, we need a stage that will not be disturbed by these impulse signals. The reason why many phono stages seem to make records sound noisier than other is down to how well (or not) they handles these signals. This is one of the reasons why valve phono stages can often be better sounding than solid state ones, the power rails of a typical valve phono stage are in the 250v area, this gives far more headroom than the typical 18v supply in a solid state unit. So, we need to handle impulses which can be up to 40dB (100 times) above the normal level. So we need a front end that can handle signals from 100mv to below 10nv, a 140dB S/N ratio. Not a simple task.

To provide the huge dynamic range required of a signal from a cartridge we use an innovative circuit that makes use of the best of the valve and solid state world in conjunction. A ultra low noise pentode (D3a) from the last days of valve technology was at was at its peak, is used. This combined with an active load and output buffer with self adjusting stabilisation circuity means that super low noise, low distortion (good as most solid state design), wide bandwidth (DC to over 1Mhz), high slew rate (can swing 60v at 300kHz), stability from component aging and large overload margins makes it the ideal front end for any phono stage.

Once we have amplified the delicate signal from the cartridge, we now have to apply the RIAA equalisation. While many designs split this EQ over two or more stages, or use it as part of a feedback look. We believe that the best sounding RIAA is done in a single stage, using no overall feedback loops. Further to that we believe the best sounding RIAA can only be achived by the use of a LCR T-Network. Unlike most RIAA stages that employ just resistors and capacitors a LCR design adds carefully chosen inductors to the mix. By the addition of these inductors, it becomes possible to create a network that provides the accurate equalisation needed, while also (and most importantly) provide a fixed impedance load to the driving stage. It is this constant impedance characteristic that allows LCR based phono stages to produce the uniquely realistic and transparent midrange and detailed bass response that only they can achive.

While the LCR network provides an idea solution, driving it from the preceding stage has often been the problem area in previous designs. In the case, the innovative first stage we have already described, provides the ideal solution to driving the LCR network.

Once our precious signal has been through the LCR network, its up to 100 times smaller than before. So we again need to amplify it and make it ready to drive the following system. Now we use one of the best sounding 9 pin valves, the 6072a dual triode, we use this valve for the same reason many other top designers use it, it provides good gain, low noise, and good sounds. In this case its used in a active load (SRPP) configuration. This stage then feeds an output buffer. We use a 5687 triode for this job. This is just one of the best output buffers around, and we make no apologies in using it once more in this design.

So, that’s the amplification part of the design, but anyone who knows our previous award winning products will know that at least 50% of the sound of any design is down to the quality of the power supply (well, maybe 75%). So we have not skimped in this area. Each channel board in the phono stage contains two independent low noise high voltage shunt regulators to provide the cleanest, quietest power to the circuit. We don’t forget the heater supply either. Two stages of heater supply regulation is provided on each phono boards, each with a dedicated supply for the input valve.

Given that we are dealing with such minute signals, it would be foolish to put all this circuity next to the mains transformer (and the box would have to be huge, as it is, its full). So we have made this a two box design. Not wishing to allow any noise into the phono casework, the power supply contains first stage high voltage and heater regulation, reducing the power rail noise and ripple to the sort of levels that would normally be accepted for many traditional designs, but here is just the input to the primary regulators.

To connect the two boxes, we use industrial connectors designed for the purpose, with voltage and current ratings that exceed what is needed here, so will provide long lasting service. The casework of the two boxes are non magnetic to avoid interaction with the circuit, while providing shielding for the precious signal. All the components are chosen with their sonic characteristic as well as their electrical suitability. Charcroft Z Foil resistors provides the cartridge loading, and Takman carbon and metal film resistors are used through the signal circuity. Elna electrolytic and Mundorf film capacitors are used throughout the circuitry.

The Reed Muse 3C turntable was in use in this room and a very imposing presence it made. This turntable can within minutes be user converted from belt drive to idler drive – possibly a world first.

Reed say this about their turntable…

“After more than three years idea-crunching and countless man hours of CADing, prototyping, programming and real-life testing, we built our first commercially available turntable – Reed Muse 3C. Is it somehow unique? Well, yes! Whether you are fan of friction-driven turntables (the famous Garrard is made that way), or if you think that the right way to build turntables is to use a pair of motors and a belt, Reed Muse 3C should catch your eye.

Thanks to its unique and innovative design, you can convert friction-driven turntable to a belt-driven machine in 5 minutes.

What is inside of our turntable?

After extensive prototyping and long-term experiments we came up to a solution of using a reverse sliding thrust ball bearing for a main axis. Bearing ball is made either from steel or ceramics and the lateral stability is achieved by using very durable and low-noise polymer sliding bearing. Symmetrical drive system is designed to avoid radial bearing load, hence minimizing possible mechanical noise and ensuring longevity of a master bearing.

Muse 3C is powered by two direct current motors and by design is friction-driven, however its major innovation is possibility to convert it to a belt-driven system in minutes by replacing traction rollers and putting on a belt (and, of course, setting a switch to a correct position). To prevent possible mechanical vibration, we use traction rollers (be it friction or belt) of different diameters, spinning at different velocities and having mathematically non-multiple diameters to driving disc diameter. Disc velocity is stabilized by quartz-based phase locked loop (PLL) system, so average speed deviation depends solely on the parameters of quartz crystal. Turntable drive is equipped with both mechanical and electronic protection systems.

Turntable also features electronic inclinometer (electronic level dedicated to measure turntable slope/tilt angle), which allows user to achieve perfect horizontal alignment without using additional tools.

Turntable can be equipped with one or two tonearms with effective length ranging from 9.5” to 12”. To ensure accurate tonearm mounting we include 500 EUR worth SMARTractor, made by Acoustical Systems (

Audio Emotion – First Floor Becketts



Zeta Zero a relatively new Polish company had their UK brand launch within the Audio Emotion room, and very interesting the Venus Picolla £1999o (speakers on the inside edge of the system in the photo above) looked too.

Zeta Zero say this about themselves and their speaker designs…..

” One of the very best high-end loudspeakers systems ever made in the opinion of many experienced audiophiles. Unique cutting edge new powerful TRUE ribbon transducer ultra wide-band  technology, extremely durable, with incredible sound parameters, and very advanced electronics, placed in beautiful 21st century new-age solid wood cabinets. Created for the exacting music lovers who want to transform their luxury living rooms into spectacular home theatres of wondrous sounds & visions, and sensations never known before.

ZETA ZERO is therefore a combination of ART & performance, custom cabinets hand-created from wood, combined with a large number of components for optimized sound. And everything brought together with an almost unlimited power reaching up into kilowatts, and unprecedented dynamics unheard of in domestic audio systems. This symbiosis of features is usually absent in the typical high-end offers, whose common complaint is that they offer weak power , low efficiency and very high sensitivity to any overloading in return for good bandwidth. Due to the advanced materials and innovative solutions, ZETA ZERO are able to combine these contradictory features , and effectively remove these known limitations and disadvantages.

As a result, ZETA ZERO speakers performance is the answer for all those looking for something outstanding in the sea of mass-produced audio equipment. At least that is the overwhelming opinion of our customers – in their view- incomparable sound. We have dedicated our construction to music connoisseurs who appreciate luxury and a new dimension in perfect sound- those biased against the normal, often imperfect offers of others’ audio sound, those ready to go that extra mile to hear good sound. Thus many years ago, with this in mind, we created an engineering research project – ZETA ZERO to overcome the contemporary sound barriers specific to the speakers currently on the market. In fact, according to some listeners ZETA ZERO is in effect the equivalent of a Formula 1 race car.”

Also on show was the new Orbitals omni speaker design from Zeta Zero, so new there is still no info on their website about the speaker.

RMB Loudspeakers – Ground Floor S7


A fairly new name to the UK loudspeaker market, British company RMB exhibited a number of their unique designs.

RMB say this about themselves…..

“We hope it will lead to an enlightening audio experience. Many of the finer material things take a little time and effort to seek out. So it can be with audio equipment , and for the time being our speakers are only available from us direct, (at very advantageous prices).

How to reproduce a musically pleasing sound from a domestically acceptable cabinet? Something that has aspects of the extra – ordinary, that is demonstrably better than the “average”.

RMB loudspeakers may be considered to be minimum compromise designs in their respective price ranges. We strive to create products that provide the best sound at the most sensible prices they can be offered at.

Our key principle is minimum corruption of the musical signal , allied to very careful design employing superior grade components. Every aspect is engineered to deliver the optimum sound for people who just want to hear more of their music.

In simple terms, we aim to give you; Superior clarity of detail, speed, dynamic range, soundstage depth.

These qualities typically manifest themselves in the ways described below.

  • The tunefulness and tactile nature of the bass frequencies.
  • The ability to reproduce percussion sounds and speech without smearing and with minimal compression.
  • Fresh awareness of subtle details from familiar recordings – (this is a common observation voiced by our customers).
  • A sense of depth and height to the soundstaging. When partnered with suitably capable equipment, an impression of the speakers seeming to “disappear”. (this term is often used in audio reviews, but it is a pleasing illusion rarely enjoyed by most listeners).
  • Crescendos and sudden transients in the music should be exciting and cause for a smile! sadly, many “hifi” loudspeakers reduce them to something resembling a muffled sneeze from the audience.

RMB loudspeakers provide these essential dynamic contrasts even at low listening levels and invariably prove to be highly revealing of the partnering equipment.

We could go in to detail about only using drive units from specialist manufacturers; decades of R & D bear fruit in the sound characteristics and consistency.

We could tell you about the capacitors we insist on using in our crossovers that cost about five times as much as standard types.

We could explain why we only use a specific type of cable for the internal wiring.

We could tell you about the complex and over – engineered cabinet design.

However, such technical points are of little importance unless they contribute to a special and superior listening experience.”

RMB exhibited the Model 22/3 £1850, and the Model 40/4 £3000

The Clarity Alliance Showcase – First Floor Luffield Suite





This room housed the launch of a new UK based audio company Kleio Audio and their first audio products, the K105 pre-amplifier and the K135 integrated amplifier.

Kleio Audio say this about themselves…..

“In June 2010, whilst researching headphone amplifiers, I was given the idea to build my very own having always had passion for both hi-fi and music since I was a teenager. Shortly after I began this process, I decided I wanted to go one step further and develop my very own range of hi-fi components. The opportunity to combine both my passion for music and my interest in UK based manufacturing has been hugely exciting.

Two years later Kleio was formed, with a simple concept to design and build high-end audio which makes music enjoyable.

Today we are pleased to announce the arrival of our first two products from our K1 series, the K105 and K135. Both products are crafted in the UK as a result of over 3 years research, development and engineering refinement. A high percentage of internal components are sourced from the UK and Europe.  We are also proud to be part of the official made in Great Britain campaign.


The K1 series components are machined from a solid aluminium billet and will all be supplied with a 5 year warranty. The next few years will see the arrival of many more products to join the Kleio family and we look forward to sharing these with you as our journey continues.”

Kleio Audio say this about their K105 £3000 pre-amplifier…..

“The K105 is our first ever pre-amplifier. Built on the basis of solid engineering practices, which include the use of relay switching throughout and short signal paths. The K105 is built using carefully selected components before being hand soldered at our dedicated manufacturing facility in Kent.


We understand the importance of connecting multiple audio sources, which is why we have supplied multiple inputs including 4 sets of RCA inputs, 2 sets of balanced inputs and a 3.5mm connection.  A selection of line level outputs are also provided, one set of which is balanced.

The minimalistic design is made possible by the use of a dual action volume control. The pre-amplifier can be switched on and off by pressing the volume control. The stylish design is completed with attractive white LED’s displaying your chosen listening level and selected input.”

The £3200 K135 integrated amplifier is……

“Based around the same solid engineering principles as used in the K105 pre-amplifier, including the use of relay switching throughout and short signal paths. The K135 is crafted from carefully selected components before being hand soldered at our dedicated manufacturing facility in Kent.


We understand that an integrated amplifier should offer the convenience and quality of pre/power amplifier set-up.  With the K135 we have fitted 3 sets of outputs plus multiple inputs including 2 sets of balanced inputs and a 3.5mm connection. A high quality Class D power amplifier is used to provide 2x 65w (at 8 ohms) of power.

The minimalistic design is made possible by the use of a dual action volume control. The amplifier can be switched on and off by pressing the volume control. The stylish design is completed with attractive white LED’s displaying your chosen listening level and selected input.”

Both of these products look very interesting and a new UK based audio company is very much something to welcome. According to Garry Wise (Kleio Audio’s MD) in 2016 there will be a stereo power-amplifier K125 and a mono amplifier the K115.

I personally look forward to seeing how Kleio develop as a brand and perhaps at a future show having a listen.

Sound Link Pro Audio – First Floor S22


Sound Link Pro Audio –



As I didn’t attend this show I can offer no feed back in regard to sound quality in the varying rooms but having gone through the list of exhibitors, it appears to be marginally smaller to last year and quiet a bit smaller than in previous years.

Its obvious too how many and which audio companies are no longer exhibiting at NAS, that did in previous years but I guess that’s to be expected as priorities and budgets to do such things change but it is a sad reality that NAS is no longer what it once was.

In saying the above though it is nice that NAS still exists and that the show is to a degree moving with the times in that it has put HeadZones – the dedicated headphone aspect of the exhibition – into the Brookland Suite thus giving this healthy and growing sector of audio a much more prominent place in the show. Such a move is to be applauded and hopefully many getting into this aspect of enjoying music, who come to see this part of the show, will not only migrate into the more traditional side of things at the show, but also at a later stage purchase such to listen to their music on too.

Hopefully I will be at NAS next year.
