Kirkus - class A amp at very low levels has both output devices conducting simultaneously doubling their voltage gains. It creates wobble in output linearity - no escape from that. It is known as "gm doubling". Increasing bias won't help since overbiasing creates higher order of odd harmonics (because of gm doubling)as well as underbiasing.
Why are most High End Amps class A
Hello, new here and wondering.
I've recently been looking and reading at Audiogon and see that most "High End Amps" are class A. Currently I own a McIntosh C28 preamp and MC2105 amp. To me they sound fabulous.
Would a "High End" class A sound any better?
Of course I realize that there are very expensive class A's that would blow away my Mac's, but what about say a used class A in the $ 1000.00 to $2000.00 price range?
Thank you so much for your input!
