The 501 does not have preouts. I'd suggest the Denon 2803 or the newer 2815 or 2115? These should provide more power (although I'm not sure if you really need it) and have pre-outs if you get the more power is better bug. The 2803 can be had for a pretty good price. I would wager that if you wait a few months you can get Denon's new amps at a discount through ecost and the like.
