I've owned many excellent class A amps. I've settled on a class AB and a class D integrated for my systems and they produce the best sound I've experienced in my home. Topology certainly doesn't tell the whole story of what an amp sounds like.
Class A amps
I've read a few articles on class A amps but still don't have a good understanding of how it affects sound quality. I've even seen amps which can be swithced into class A mode or AB. Does anyone have experience with this type of unit? Does class A have a true audible advantage or can it be detected only by test instruments? If it is audible, in what resepects? Thanks, Rick M.
