Re: class AB vs pro amp

I agree completely with what Dawnrazor stated. You *need* a high current amp to get lively sound out of a pair of Maggies. I already mentioned the following in a previous post, but answering your question may be a better venue for this question.

Would anyone claim that class AB was created as an improvement to the fidelity of class A? Nope, it's all about efficiency. I suspect class H (or class D, or...) is to class AB as class AB is to class A (all about efficiency). Then again, I cannot make any statements about the relative merits of pro amps because I have *never* heard one. I did buy a Carver M400t (all about efficiency) once and I didn't like it (one motor-boating (among other things) little SOB).

I don't profess to be an expert, but I think a quality class AB amp with low, uniform output impedance, high current capability with deep tanks (big caps), and smooth, wideband frequency response is the better solution (than a pro amp). One doesn’t have to break the bank to obtain such an amp either. I’m not suggesting that I own the ideal amp, but I picked up a nice Acurus A200 that meets all of the aforementioned criteria for under $500 (even came with a monster of a PS Audio power cord). It’s a very simple amplifier design with very little global feedback – straightforward and solid. It’s not as refined as a Pass, but it wouldn’t be embarrassed by one either; it *would* embarrass a Carver amp – that much I guarantee.
