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

As someone who earned a living as an electronics technician, I am qualified to state what is "theoretically" better. While Class A is theoretically better, you need the hearing of a good hound dog to tell the difference between AB and A; maybe some young people got it, but I'm very doubtful about old folks.

What some old folks got is "deep pockets": deep enough to entertain their fantasies.

If I was rich, I would still have high quality AB, because I'm certain I can not hear the difference, so why pay so much just to heat the house.

Dan D’Agostino's son Bret certainly agreed with your premise & his co. Bully Sound still has their site up even after his demise so presumably they're some kind of going concern >

Inna, some people can hear better than others in regard to Class A.

In regard to SS versus tubes, some people are music lovers, and some people are equipment lovers.

When I had an audiophile music loving friend, we swore by our "0 distortion" SS gear. I requested a CJ preamp to audition at my home, and invited my friend over for his evaluation.

The CJ was a loaner and produced apparent distortion, but even through this distortion, we both agreed that the music sounded better. Neither one of us has ever considered SS preamps, since.


However, an SS power amp simply reproduces the signal of the preamp; consequently, a high quality SS power amp is acceptable.

While I don't feel strongly enough about class A vs AB to become a television evangelist so I could spend a few billion to hire the Islamic State tosteal for me a Tzar Bomba to use against people using AB amps, I make my own class A tube amps because they are simpler to build and you can for a few hundred dollars buy parts as good or better that what you get if you spend five figures on a high end tube amp. I like my Magnepan speakers so I solve the sensitivity issue by using radio station transmitter tubes. If I use 45s by themselves I have to use sensitive speakers.But I have heard some fine sounding AB amps too.

"Why would women want audiophiles when there are better men ?"

Because we are better listeners
