That’s the big problem I’m trying to figure out is outside of a reviewers measurements how to determine what the real power going to all the channels is. My Denon 2807 is rated at 110x7 and I can play 2ch music up to 105dB without a problem, however in a demanding multi channel scene it starts clipping/distorting way below that.

So I need to know for sure how much say a 120 watt Denon can really deliver to 7 or 4 channels. 7 if I used it stand alone, and 4 if I used it for the just surrounds/backs. Above 120 watts the price really starts going up fast.

OTOH if I do end up getting the Outlaw 997 then I’m going to need amplification for all 7 channels.

As for pro amps, I will warn that many lack RCA inputs, so you need XLR converters if you don't have a separate pre-amp.


Good to know. I’ve checked out the Behringer A500 mentioned by fred and it looks promising. But now I need to start figuring out what other specs. in an amp are important. For instance what are good numbers for S/N ratio, crosstalk, frequency response, THD+N and anything else I‘m leaving out. Also in which direction are those numbers better and worse. I’m assuming smaller is better for the ones I mentioned. Plus, is there a sort of cut of were a better or worse number isn’t really noticeable. And how does the amp design A/B etc… effect it’s performance in various roles. I guess what I’m saying is I really need a good primer on amps but have yet to find one.

Basically I don’t want to pay for a bunch of power I don’t need while ignoring other factors that may be more important to me in the amps performance.

Thanks for bearing with me on this guys, I’m usually not this dense. ;\)
