Well, the Crown amp experience was helpful. I know I want an amp, but the Crown's noise floor is too high (S/N is about 90, and THD is around .5%). Researching a bit, it looks like the QSC is a better option for my uses. QSC actually has several THX certified amps using their H-class amps. THX Cert Their noise levels are much lower (S/N >100 and THD is <.05). I can't find the THX amps locally, but the GX line uses the same H-class amp design and looks similar so I'm going for it today. I'll let you know.

But I have to give the Crown two thumbs up, other than a bit of noise during dead quiet sences, it is great. Hopefully the QSC will do the same without the noise.
