Why would anyone want class AB amp when class A always sounds better ?

The Plinius amps of yesteryear allowed users to utilize an A or A/B button on the front of the amplifier to allow for Class A critical listening. The amp generally sounded its best in Class A, but A/B was very close.

I don't know if the current generation of Plinius amps allow for such user friendly options. 

"I might be off here, but class A amps don’t drive lower impedance speakers very well either. Most class A amps aren’t stable into 2 ohm loads. Krell being one Of the exceptions."


Yes, you're way off. Ever hear of a well known audio company called Plinius?

Hmm, I don’t get it. When I owned a Plinius SA100 mkiii amp the difference from class A listening to A/B was like night and day. The amp of course does both Class A and Class A/B. It’s as if the lights were turned on. I’ve owned lots of Class A from Threshold T400, T200, Coda, Pass Labs, Plinius, and it wasn’t until I switched to tubes did I begin to here something different.


But SS Class A is as good as it gets to my ears. To those that can’t hear a difference I feel a bit sorry for you for you don’t know what you’re missing. Class A is where it’s at. Whomever suggested Class D was better than Class A suggests they’re in Audio training and haven’t had their training wheels removed.
