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).

@zm
Which FirstWatt model are you comparing to?

Each of them have a different circuit topology and output transistor types, SE, PP, different impedances, and wattage power output. Interested if your AA Pucciini sounds more like a SIT-3, F6/F7, or J2, etc. Also dependent on what preamp you are using too. Thx.

@decooney I am comparing to an F2/J, which is an F2 modded by Nelson Pass to replace the Mosfets with power Jfets.  
I have an SIT-3 coming on Tuesday, after which I will be able to comment on any comparison there.

Preamp is LTA MicroZOTL MZ2.

@zm Thx... the Pucini was on my list for quite some time... but after reading reviews about it, I concluded that it was pretty similar to my Sugden...

The BellesAria is 75watts, is really open sounding and has good grip on the bass.  Its a beefy 75 watts for sure.  It might be slightly rolled off on top but has a nice warm sound that is not fatiguing at all.  
It is lightweight and unassuming but is of great quality.

@hilde45, the inside of that atoll is top notch 👍
