Well after going over the manuals for my receiver and for the new amp, as well as taking some output voltage measurements I figured out that the trigger on my receiver will not work with the trigger input on the 7100 amp. No problem though, I simply added a 12v DC converter to one of the switched outlets on my receiver and plugged it into the amp ( same as outlined in the 7100 manual), works fine now.
As for how it sounds, I have not had a great deal of time to do any real critical listening yet. My initial thoughts are that the amp does a great job of powering my Polk Lsi's, which are 4ohm nominal. I will start another thread after I've had a chance to listen to it some more.
