Pick a price and features then look at the usual suspects we talk about, Denon, yamaha, onkyo, H/K, Outlaw, nad, etc. and go with the one you feel is the best bet. They all work extremely well and it is highly unlikely anyone would be able to tell the difference amongst anyof them at the same volume levels with in each amps limits(this is the key part). If you put a 100w/ch amp in a huge room and then put a 400W/ch amp in the same room and play each at 100db the 400w amp is going to come through with better dynamics/less distortion etc.
