Tom Evans Audio Design

Technology is wonderful, but when it comes to real innovation - something which is completely new, one designer comes to mind more often than any other - that is Tom Evans.





If you know anything about high quality phono playback, you must have heard about the now-legendary Tom Evans Audio Design Groove Anniversary SRX  and Groove Anniversary Plus SRX phono stages. To give you some basis for comparison, I recently compared the Groove Plus to my Boulder 2008 phono stage. Remember, the Boulder sells for $32,500 and the Groove Plus a mere $7,600. The result: The Groove Plus was ten times quieter and sounded infinitely more life-like than the Boulder in every possible way.

  Just when u thought it could not get any beetter Tom has unleashed 7he finest solid state ohono stage in the world 'THE MASTER GROOVE


 Not just a pretty face, the Master Groove extracts nuancesfrom your vinyl you never knew were there .Texture, harmonics , speed and dynamics--just amazing!



Following on the Groove Plus, Tom Evans created the Vibe line stage, the Pulse power supply, the Linear A amplifier and most recently, the Linear B mono amplifiers ($16,000/pair).

It would be impossible for me in this limited space to give you the complete Tom Evans story. Besides, you can probably get as much as you want from clicking onto and looking up the reviews of the Tom Evans Audio Design Linear A stereo amplifier in the August 2005 issue or checking out their December 2005 review of the Tom Evans Vibe Lithos 7 preamp & Pulse power supply.

The Groove dual mono phono preamp uses one Lithos 7 regulator per side to supply power to each mono signal circuit board. All resisters are Holco precision metal film, all silicon is of premium grade. The regulators are all powered by a dual mono mains power supply. Since its launch in the UK it has become the industry standard. The Groove can also be upgraded to the PLUS spec!


The point, as made in the former review is, "Each one of these products is unique in concept & design compared to anything else I am aware of. These Tom Evans designs are the real deal. They are true originals……”

Or in the words of my friend -- TAS reviewer & fellow moonie Stephen Harrell -- after hearing the full suite of Tom Evans equipment in his own system, "This isn't just HiFi; this is stupe-Fi-ing!"

As we both were in our respective systems, you'll most likely be stunned too when you hear the whole Tom Evans stack of gear playing "the tunes."


Just as an example of the extraordinarily and innovative ideas incorporated into Tom Evans products is the fact that the Linear A, a single ended class A ultra linear device, arrives at creating the effect of a legendary and virtually unavailable Japanese tube by combining four single ended EL 84’s per side linked in parallel. What a brain, that thought this up!



The Lithos 7 preamp is encased in Perspex, not to save money, but precisely because acrylic avoids trapping inside of the component the magnetic fields created by the mains power transformers. No capacitors, all DC coupled.

The source selector is a Wesex advanced switching product (WASP). Why? Because it is the best in the world. Same for the DAC volume control.


The Tom Evans Linear A and Linear B amplifiers are truly revolutionary, groundbreaking designs.

Both the Linear A stereo amplifier and the Linear B monoblock amps are ultrawide bandwidth designs with vanishingly low levels of distortion. More importantly, unlike some other amps with those same two qualities, these amps are incredibly involving and a joy to listen to.


The Linear A is a single ended, Class A, ultralinear stereo amp with a power rating of 25WPC. Four EL84 tubes per side, in parallel, create a composite tube with characteristics almost identical to the legendary Japanese No.10 tube. The amp measures as an almost perfect model triode, promising to deliver the often sought but rarely realized linearity benefits of triode topology without it's usual limitations.

Paired with an appropriate speaker, this amp can do it all in a way nothing else in our experience has ever been able to do; luscious midrange combined with rarely realized frequency extension. The absence of distortion has to be (not) heard to be fully understood. The clarity and detail retrieval are astonishing, but not at the expense of musicality. It's a combination of qualities we have never heard outside of the two Tom Evans amps. We invite and welcome comparison with any amp in the world, at any price.




Consider what Jeff Day wrote in his review of the Linear A, "They represent the most startling advancement in the reproduction of music that I have experienced in my also represents the most significant advancement in the reproduction of musical realism that I have encountered short of sitting in with a'll most likely be stunned too when you hear the whole Tom Evans stack of gear playing the tunes....simply the finest amplifier I have encountered in all my years in audio."

The Tom Evans Linear B monoblock amps differ in design from the Linear A stereo amp. The Linear B is not simply a monoblock iteration of the Linear A.

The Linear B is a push-pull fully differential design. Listening comments which apply to the Linear A also apply to the Linear B, but more so.
