Hi all,

Have been searching the forum for a clarification of Class A amp and Bias to Class A, but still not sure what it is.

What is the different between them? I own 2 Meier-Audio amps which are claimed that their Opamp are biased into class A. Then what is also the different in term of sound quality? I presume that a pure Class A may sound better than the biased one.

Thanks for info,
Kenta

PS. There are some mentioning about Class D. I recall from the Nuforce website that some of their amps are Class D which consume very low power and can be left on.
