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).

Great way that will sound very good, would be a $799 Schiit Aegir 20w Class-A for the highs and a $699 Schiit Vidar 100w a/b for the bass, horizontally bi-amped. Which if you look at the Altec xover is a snack to do.

You will need though a Schiit $49 Sys passive on the Vidar input as it has more gain than the Aegir and needs to be lowered just a bit, and this will allow you to tune the sound a little to your room or yourself.

ayre

are the purest sounding high power ss amps i have come across

at lower power/current delivery level it is the audiosector patek se gaincard clone of the original 47 labs unit

i have not heard a dagostino, goldmund, symphonic line amp in my own system
In taking a closer look at your setup I noticed the Sugden only has single-ended inputs and you’re running a 12’ interconnect between it and your DAC.  I’m not sure how much impact this might have on your sound or if the Benchmark has the juice to push the signal that far without it degrading, but if I was running interconnects that long I’d be using balanced interconnects — obviously not possible in your case.  Maybe others can opine more in depth about this, but just thought I’d bring it up as a potential issue. 

That aside, I think you’re pursuing something of a unicorn given what you’re looking for at under $2k and excluding both Class-A amps and tubes.  
@audioguy85 : my place gets way too hot in summertime to use a class A... also, it seems pretty irrational to me to waste so much electricity... I was told by a tech that what damages an amplifier was everytime you turn it on and off... when an amp consume very little at idle (or on a stand-by mode), why not simply leave it on all the time?

@jjss49 thx for introducing me to Audiosector... I will definitely check that out...
