Take a look at Wright Sound (http://www.wright-sound.com/). He makes 300B, 2A3 45 SET amps, as well as a couple of push-pull amps. I have a pair of his 2A3 monoblocks (as well as his preamp), and I am VERY pleased!
From a survey of 12 single-ended amplifiers, Listener, Volume 5, Number 4, Autumn 1999:
"Mr. Wright's 2A3 SET is the most neutral, accurate, and -- equal to the Welborne Moondog -- musical amplifier of the survey. This is a very speclal product. Each and every listener did a double-take with the Wright WPA3.5 in the system: It's that head-and-shoulders above the others.
What came across first was the WPA3.5's purity. Leading edge transients on all the recordings catapulted from an acoustic so clear I could identify the ambient space in an instant -- whether a simple studio recording, multi-microphone orchestral, or anything in between.
I've also never heard this clarity of a note's attack component before -- but the Wright doesn't "favor" it: The same clarity continues into the sustain component, re-vealing the harmonic structure of each instrument, and then follows into the decay. The best amplifiers "even out" each of these three components of sound rather than highlighting just one or two -- and the Wright is far and away the best amplifier of the survey in this regard.
The Wright isn't just clear -- it's harmonically "right." When something is correct in an area of your expertise and interest, you just know it: Some internal bell is rung and, bingo -- the light goes on! Listen to this amp and you'll get it. In fact, if you're like me or any of the other listeners who heard the WPA3.5 in my home, you'll be awed.
