Should I buy a Class A Amp.

Could it be said that Class A amps, like Pass for example, play better on certain types of music? Better classical than rock, for instance?

As mentioned earlier, no.

The idea that an amp can be better at one form of music as opposed to another is one of the bigger audio myths out there.

Actually, it was I who asked this question, and I had not ever heard this said before, myth or otherwise.

Fact is, with my Pass XA30.5, that is exactly the impression I get. Better on some types of music than others. Relatively speaking.

atmasphere +1     Besides the amp, don't forget the speakers - the cabling - the power delivery - the room - etal - play a significant role in how the music comes out.  If one type of music sounds better than another, any number of variables can affect that perception.

Ideally there should be no difference for an amp to play any kind of music equally well. In reality, there is. You don't want Kondo to play jazz/rock fusion. Some amps manage to strike a good compromise. But it's not only amps, it's also speakers etc. If I could I would have two completely different set-ups - one tube, the other either solid state or hybrid or also tube but different.
Atmasphere's mythology is that there are no better amps than his and no better ideas than his. I'll leave him to that.

What preamp do you have?
