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).

The Benchmark distortion at low power, i.e. where crossover distortion comes into play is every bit as good and probably better than most Class-A. Same would be true of several new Class D amps.


Nothing repeat nothing! solid state A/B (low bias A) sounds like a 20w> high bias Class-A amp.
As there is no xover distortion in Class-A when the top and bottom transistors switch over from each other, because they’re still both biased into Class-A.

Luxman M-900u is tha best. 150 W. RMS Will make any PassLabs class A amp sound broken...

First 12 Watts high bias class A. With most speakers, you never get out of the class A range.

FYI, for anyone following this thread, I've decided to sell my Atoll IN200 SE. If you're interested, feel free to p.m. me.
