need help deciding between these 2. same price and all the same features. denon seems to have more power but yamaha is considerably heavier (better build quality?) i could really use some input from those of you experieced with these receivers. FYI, haven't had a system for quite afew years and am really excited. thought i'ld start with rec. and a couple cm8's and go from there. i appreciate any imput, thanks.
