Masterpiece Pre-amplifier

Masterpiece Edition pre-amplifier

Designed around the MV2 Pre-amplifier but taken to a completely new level in terms of component specification, vacuum tube choice and internal wiring to give an even better sense of musical involvement and resolution.

The Masterpiece edition Pre-amplifier has an extremely simple and pure signal path with only 1  output capacitor and 1 shunt resistor on the Khuzmo stepped attenuator which have been replaced with the incredible V-cap CuTF reference capacitor and a Charcroft Z foil resistor. This along with 5N solid silver and FEP fluoropolymer signal wiring gives this Pre-amplifier added  realism and an even better 3D soundstage capable of competing with the very best equipment in the world.

The choice of Linlai Global Elite vacuum tubes also elevated the sound field beyond the previous Black Treasure tubes.

Design specifications include dual mono power supplies with each channel supplied by it’s own high voltage and filament rails via a tube rectifier and feeding separate regulators to give incredible stereo separation.

A very simple but pure signal path based around the 6SN7 audio tube and using a single output capacitor which can be specifically chosen for it’s integration to solid state or valve amplifiers based on input impedance compatibility.

Masterpiece Edition Pre-amplifier features :

  • Dual mono design
  • Lineal Global Elite vacuum tubes
  • Khuzmo 48 way stepped shunt attenuator with Charcroft Z foil shunt resistor
  • Ohno Continuous Cast unicrystal silver 5N wire internal wiring
  • V-Cap CuTF output capacitors

Purity of signal path is critical in the design of any amplifier to give incredibly black backgrounds and the retrieval and portrayal of the tiniest musical passages and notes.

Masterpiece Class A Monaural Amplifier

Masterpiece Class A Monaural Amplifier

Class A amplifiers have always had the reputation of warmth and a great soundstage and although class D amplifiers have made a great way forward in recent years, is there still room for this old design of amplification in the modern world?

Excessive heat, high power consumption,  low damping factor and relatively low output power. All these aspects  does not bring confidence to the discerning audiophile how-ever as always, it is in the listening where this approach to amplification brings a certain joy and pure audio realism that answers the question earlier.

My own reference system now utilises these monaural amplifiers along with the latest Masterpiece Edition tube pre-amplifier and in terms of preference the MB10 Class D  mono block amplifiers which are incredibly good, now comes  behind these amplifiers.

The reasons are many but primarilly it is about that elusive holographic presentation, a lack of edge to vocals and instruments such as piano and pure realism to live recordings which gives an accurate sense of space and depth to a recording. 

Digital recordings have a more organic and analogue feel and vinyl takes on an even more beautiful and beguiling nature making you want to explore  your vinyl collection yet again and buy new records.

As with all the masterpiece editions, this model is hand crafted using exotic materials and components. Bolivian Rosewood, copper panels and silver wiring are standard.

Argenti Ultra Streaming cable

Argenti Ultra Streaming cable

Robson Acoustics has been in the streaming music business for over 12 years now and this is an area which is well established how-ever still provides chalenges especially in streaming music which ultimately comes from a source of data entering our house and sent to our devices through a router. A simple house router is not designed to provide clean digital transfer and so it ultimately comes down to knowledge and experience to remove as much as this degrading noise and interference passing between the router and your precious streamer or digital playback device. 

The digital Streaming cable is probably the most important chain in this search for audio nirvana along with a simple buffer between the router and streamer such as a network switch which re-clocks the signal and eliminates some of the noisy artefacts coming from the router. There are many good switches on the market and we currently sell the excellent Chord English Electric 8 switch. 

The quality of the streaming cable is extremely important and it is quite easy to do A/B comparisons between such cables which is why our new streaming cable represents very good value for money and provides a clear upgrade path for your streaming solutions. 

Made with silver plated high purity copper stranded cable with 4 layers of screening and finished with very high end plugs from Telegartner. Very flexible and with can be hand made in bespoke lengths.

Reference Digital Cables

Reference Digital AES and RCA Cable

The last few years has seen a huge increase in digital music whether streamed computer or from a CD transport etc. The importance of a good digital cable such as this AES or streaming cable is very important and all helps in eliminating the digital noise and distortion associated with this form of music replay. Quite often, replacing a cable can make a bigger difference than replacing the DAC, streamer or CD player.

Having listened to many high end cables and experimented with many different designs, the Ref digital AES cable is the culmination of years of searching for a truly spectacular cable design which will compete with much more expensive cables as all the Robson cables are capable of.

Robson Acoustics have a new range of cables designed around not only extremely high purity (99.999% or 5N) conductors but also insulation which gives a very low dielectric coefficient of 1.4. This foamed and cellular Fluoropolymer construction is now a standard construction design in nearly all our cables and responsible of the outstanding performance obtained from this and other products.

Solid 24 AWG pure copper wires with minimum twisting and with FEP insulation. Natural unbleached cotton, PTFE tape and an ultra flexible core material are used to create a natural buffer for mechanical resonances. The outer shield of silver plated copper is as far away from the critical signal conductors as possible. 

Finished with very high end Rhodium plated XLR plugs for that critical high resolution digital transfer.

New digital RCA cable now available. Details to follow soon......

Reference Infra Subwoofer

Reference Infra Subwoofer

From the early stages of Research and Development into a no compromise standalone subwoofer, it was apparent how vital this element of a home Theatre set up played in the overall rendition of audio playback.

The essence of a great subwoofer carries the impact of low frequencies where sounds can be felt as well as heard and where sounds such as the human voice, piano and small calibre gun shots contain low frequency registers that are reproduced by the subwoofer.

The laws of physics dictate that to move sufficient air with low distortion and clarity, a large drive unit is essential to ultimate performance.

Designed around a 15" high spec dual voice coil drive unit in a complex secondary ported cabinet coupled with a 500W high current amplifier enables this subwoofer to deliver exceptional low frequency performance even in a large room.

The Robson Reference Infra subwoofer will take your senses to another dimension where your ears play only one role in home Theatre entertainment.

Voltaire III

Voltaire III

A glimpse pre-view of our latest speaker in the Voltaire range…….

Exceptional in many ways this design has virtually no cross-over and uses drivers specially chosen and adapted to give perfect integration in a 3 way system of incredible dynamics and realism.

Low frequencies are handled by a modified Volt 12” radial bass unit which takes bass control and precision to a new level and which runs completely open with no cross-over components in the signal path or in parallel.

The midrange frequencies are handled by a modified 3” Volt soft dome unit covering the most important mid band frequencies extending up to 4.5kHz crossing over to the legendary Raal ribbon tweeter to give shimmering highs only this tweeter is capable of.

The midrange unit has a single Dueland Coherent Audio cast resistor in series to lower it’s sensitivity and with a single Mundorf parallel capacitor to perfectly integrate with the tweeter.

The Raal tweeter then uses a single series Clarity Cap CMR capacitor which can be upgraded to a Dueland cast silver/oil capacitor on request.

Internal wiring has been specially chosen and using damping control and cryo frozen to give additional purity of signal path combined with WBT pole connectors.

All these components and virtually no cross-over equates to incredible dynamics and the rendition of musical passages only heard of from esoteric and extremely expensive loudspeakers.

Voltaire Zero

Voltaire Zero

Our new and exciting range of loudspeakers using the well renowned bass/mid drive units from Volt Loudspeakers Ltd begins with Voltaire Zero, a true reference monitor able to dig depths into recordings seldom heard before.

Using a critically doped 8” bass unit with high linear excursion characteristics and low midrange colouration and able to achieve very good transient stability at high sound levels.

Coupled with a highly specified and large ribbon tweeter able to crossover at lower frequencies gives the Zero much of its incredible vocal clarity and refined sound.

Superb imaging and a fabulously large soundstage are just some of the qualities to expect from these monitors along with bass dynamics only Volt are able to achieve through innovative engineering and state of the art performance and design.

In order to extract every last nuance from a recording drive units of this quality require associated components of equal stature.

Now available with Duelund Coherent Audio oil/cotten internal wiring as standard.

The SE model is also available with Duelund  silver oil/cotten wiring with a CMR Clarity cap on the tweeter and WBT connectors.

Burlington

Burlington Mkll

The new Burlington Mkll has taken many years to develop and a big achievement to supersede an already very popular design.

Based around a cabinet of high structural integrity using constrained layer damping philosophies in much of it's design and using possibly the best bass/midrange and tweeter on the planet with a cross-over that flawlessly integrates both drivers together.

As with all new designs we are constantly trying to raise the bar in terms of simple musical enjoyment  where you can connect with the music being played. The Burlington Mkll does this in a truly holographic nature! Stereo separation and the natural decay of notes are portrayed in exquisite detail and resolution. High frequencies such as cybils and the natural air and textures  around instruments give an astounding realism to  recordings especially live venues.

Although this design incorporates a single Purify Audio 6.5" driver for bass and mid frequencies, the level and quality of bass produced still amazes everyone. Capable of reproducing the lower octaves of music with extreme speed and authority.

Special attention was given to the cross-over design which uses specific components to match the drivers irrespective of cost. Additional damping applied to the cross-over board with point to point wiring, silver solder and internal wiring using 99.999% 5N OCC copper wire with Airlock insulation made from fluoropolymers.

Each base is made of 10mm steel with isolation coming from our Panzerholtz and ball bearing feet which has been proven to give a far superior isolation of loudspeaker to floor. It is essential to dampen the vibrations emitted by loudspeakers either through the air or via the ground borne vibrations with both equipment dampening and loudspeaker dampening techniques. Spikes and "soft" isolation feet generally do not work and can introduce various problems when connected to differing floor structures.

Both the stand mount version and the floor standing model will redefine the  possibities  from an audiophiles perspective in terms of sound staging, resolution and dynamic contrast.

Vanishingly low distortion figures are only 1 of many features these loudspeakers exhibit bringing  the listener closer to the " in real life" musical experience within your listening space than ever before.
