I am using 2 QSC rmx1450's(260Wx2) for my mains and a QSC rmx2450(650Wx2)for my subs. As others have posted the cooling fans are a little loud but I have mine in a custom rack with a glass door on it. To me it is plenty quiet but others like to have an absolutely dead quiet setup. Just my $.02

Roy Van Nostrand, I saw some other people posting their receivers in this thread too. Receivers are amps too They just have integrated pre/pro's as well.
It's funny, but I've been scoping this thread since it started. Interesting the diversity that's out there. But personally, I'd (now) also be curious what pre/pros (or even receivers!) that people have mated to their amps. And then cost ratio: amp(s) to pre/pro. Maybe in *another* thread some day...
