suggestion for a SS class AB amp that sounds like a class A ... if such a thing exists

Looking for an amplifier below 2K for my Altec 620A (99 db efficiency). My actual amp is a Sugden A25B, which has 34 watts/chanel in class AB. Although quite musical, it lacks transparency and details. Of course, the best amplifier would be tube or class A but I'm trying to avoid these because of the heat and the electricity bill (my amp is on all day long). My short list include :

  • Audio by Van Alstine Set-120
  • Ayre AX 7e (used)
  • Sugden Mystro (class AB)
  • Benchmark AHB2 (used)

NOTE : please, no class D since I'm not familiar with it (and pretty skeptic too).

I was curious about my Atoll A/B integrated and I wrote to Atoll about this question. They responded right away. They said,

"The IN200 works in Class A up to about 40W under 8 Ohm. The switch to Class AB is quite slow."

Possibly of interest.

The Benchmark will be by far and away the least class A-sounding, so delete immediately from your list.

But are you looking for an integrated or a power amp?

Alongside the Ayre integrated, you could look at the Belles Aria.

Big fan of Ayre.  It's got a unique sound, like it sucks noise out of the room. :)

I love them, but because it's so unique you should listen, and in particular, listen with your speakers.

Ayre does a video-cast now. Pints with Ayre.

I have the Benchmark. Its behavior is dependent on what you connect upstream. The closest you can get to a “straight wire with gain.” 

I run mine with a Schiit Freya Plus which, in passive mode, measures nearly as well as Benchmark’s LA4 preamp. If you want the buttery-smooth class A sound from it you merely need pair it with a class-A preamp.
