Cool Zimm.  Thanks for sharing.

Get a couple and see for yourself, if they have a 30 day trial that is.  Great price too. I purchased the amp with the full intent of returning it if it did not make a difference. It stayed.

Anyone have those M2200s floating around? How hot do they get?
I've been scared off by the amp manuals suggesting you have a separate 15A circuit for them, yadda yadda, tons of clearance, yadda yadda, since I don't have much of either.

Misti, amplifiers simply don't work that way; they have no capability of performing a miracle by making speakers "come alive sooner" at lower volume level. Volume is volume. I accept that the impact is driven by a placebo effect, but I do "find" more bass even at low levels (this time about 70db). They call it weight I think. The only non-placebo explanation I can offer is possibly power reserves allowing bass (without a sub) that a smaller power supply can't reach. Sames as the greater dynamic range I explained above. But that is far from scientific, and I'm too lazy to do true A/B testing for the group. That is the most surprising aspect of the external amp issue for me. There literally was more music than I was getting - 2 to 3 db of sound peaks. I didn't expect that and i think it adds something to the experience, when you exceed my old amps comfort zone of 80 to 100 watts. I must be taking the same placebo. I'm with Zimm on this one. Me too. I'm with Bug on this one.

If you crank them with music at 90-100 db average, yep, they'll get hot after about 20 min. I've kept them going alot longer than that (when 1st testing them) without shutdown. Of course, if you can stand music for that long at those levels, you're a better man than I. Mine are stacked on top of each other with about 3" clearance above. No need for separate circuits.

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.

Actually John, such an observation could be perceived if the amp has a higher gain to signal ratio than another although that is an observation of SPL and not sound quality per se.

LT61, even inexpensive amps have low (< 0.1%) THD now. Didn't BrenR put up an mp3 demo of distortion awhile back that was rather enlightening? Thinking a person can hear <1% THD is like thinking you can hear a mosquito fart at 100 metres.

Thinking a person can hear <1% THD is like thinking you can hear a mosquito fart at 100 metres. You live in Canada. If a mosquito could fart, those B-52 sized mosquitoes you've got up there would present the best chance to actually hear one from 100 meters away.
