Preamps on the other hand are usually, or at least far more commonly done in class A. Its financially practical and easier to do. It just with those big powerful solid-state amps does the parts cost bill start racking up real quick. I bet some of those big Krell's with all the heatsinking--there's probably $1,000 to $2,000 for the casing and heatsinking alone, before the guts/actual circuit are even put in it. I don't know what manufacturer's pay, especially w/ bulk purchasing, but Class A can get expensive, for what some would consider only marginal gains in performance. There are other classes, but most aren't used in home audio. Class D is about the only other one you'll see pop-up now and then. The rest are for radio frequency use and what not, and a few oddballs that are used in home audio--I think there is/was a class T somewhere. Class C,G,H, and S are the others off hand.
what is diff: Class "A", "A/B", and "B"
I am confused as to the meaning of the various categories of amps/pre-amps. Is a class A necessarily better than a class a/b or c etc. Would someone care to briefly list some of the brands that fall in these categories and why?
I know, it's a small question.
