Both the Linear A stereo amp, and the Linear B monoblock amps are ultrawide bandwidth, low negative feedback 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.

In a very comprehensive review of the Linear A and associated Tom Evans equipment, Jeff Day writing for 6moons.com, says:
"they represent the most startling advancement in the reproduction of music that I have experienced in my home....it also represents the most significant advancement in the reproduction of musical realism that I have encountered short of sitting in with a band....you'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."

.Also, Roy Gregory in Hi Fi+ issue 38, says:
Play something familiar and the first thing that hits you is the sheer physical substance and rock solid stability of the sound. This level of bass definition and transparency only normally comes from very large amps indeed. But here you have the speed and impact, the dynamic jump of a small amp. It is the solidity of the foundation that is delivering the quality, and that is a direct result of the amps ability to grip and control the speakers.
The Linear A is an exiting product and not just in the musical sense. Select your speakers with proper care (a caveat that applies if you want to get the best out of almost any worthwhile amplifier) drive it from a Vibe and ideally a Groove too, and you’ll have access to genuinely high-end performance at a fraction of past prices. This amplifier represents another huge step in the process of making high-quality audio more affordable.
Along with all the traditional strengths of a low-powered amplifier, you also get the resolution and noise performance of the other Tom Evans designs, coupled in turn to the stability, transparency and authority that normally only comes from hugely powerful and hugely expensive alternatives.
Less fashionable and less pretty than the various alternatives, it is also half their price, but get it working at its best and it’s one of the biggest bargains out there in high-end audio land.

Rarely has a set of audio components so outdistanced the competition. Anyone in the market for an amplifier owes it to themselves to audition either a Linear A or Linear B. We are quietly and happily confident that it will easily outperform anything else currently available.
