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).

On the other side of four Class A amplifiers, I found the amps I was looking for, and they run in Class AB.
Class A amplifiers are not necessarily better than anything else and maybe not with all speakers or on all music.  Decide what sonic attributes you value most and then find an amplifier that delivers those while providing enough power to really make your speakers really come alive.

Not as well know, but I recently acquired an LFD LE VI.  Hand built in UK  Extremely smooth and liquid, kick ass bass, and pleasent top end.

50 solid watts of AB, drives my 84 db spendor A4s with absolute ease. It would really pack a punch in some sensitive speakers as mentioned.

Think, handbuilt smoother sounding Naim.

I have a spectral dma 50 amp, 80wx2, a/B, sounds  dinamic and trasparent, with details, and I m very happy with it. 
They say that a j roland model one, 60wx2, can have more punch.
