Class A amps

Take it up with Nelson Pass. The Messiah of solid state class-A amplification (not you)
And why his top of the line amps are low power Class-A!! and always have been.

Aren't his top of the line amps the XS series, which are not low power.

@invalid, correct. Pass’ high end amps, (Pass Labs brand) whether class A or AB are the high powered amps. The low wattage amps (either type) are considered the entry level. 

A great class A SS amp cannot be bettered, paraphrasing.

That’s true, when you discount the class D amps that best Class A.

Want an example? How about several? Read my review of the Legacy Audio i.V4 Ultra Amplifier, which has bested ALL other classes of amps I have reviewed at Dagogo.com

Yes, but not as pure Class-A as the XA series, but they the XS (a/b amp) have large amount class-B after leaving Class-A with more crossover distortion, where the XA don’t
As he says

"crossover distortion it’s "alleviated" in A/B with some bias but NOT ELIMINATED!!, that only happens in Class-A amps"

If you were using 4-8ohm speakers that were efficient, the the XA’s would be the choice.
But if you had say the Wilson Alexia’s that are 1ohm EPDR in the bass, then the XS would be the better choice, for better current into that 1ohm epdr bass load, and class-B in the bass is fine

We listened to the Gryphon Antillion Evo, a 150w amp but it can give 5000w at 1/2ohm, and on the Alexia’s and it can do the 1 ohm no problem
It’s able to be switched from 20w Class-A bias to 40w or 100w on the fly, and all 8 of us could believe just how much better it was at 100w class-A bias.
But the room did get very hot after 1 hour of listening.

I like to see/hear any class-d better the Gryphon Antillion (in 100w class-A) in the above post on the Alexia, I’d put my house on it.
