Just got a new pair of M60's. What recommendations are there for a stereo receiver? I will not be running a sub. Budget is under $1000 US. I also may just by a stereo amp and listen to CD's only for now; so any suggestions on an amp is appreciated as well. I listened to a NAD stereo amp and cd player(not their high end stuff) with two PSB towers(T55?), no sub, and it sounded pretty good. Anyone using NAD? Thanks.
