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

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.

"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?

yes I that was said before "I might be off here" and I replied to him.
Yes way off!!

And gave the explanations why.

As no one in their right mind would prefer the sound of class-B xover distortion no matter how little.
To the same amp in Class-A (unstressed) with no xover distortion.

The doubters, should do themselves and those here a favor and listen to a Gryphon Antillion that can be switched from 10w Class-A to 50w Class-A to 100w Class-A on the run while listening. And there are others like the Parasound JC1’s etc etc

Then the persistent doubters can hang their head in shame for even suggesting Class-B can sound better than Class-A if all is equal.
