Hi guys. I have a crown xls 1500 and plan on getting a few more for my system down the road (for all channels in a 5.1 system). From a cost and feature standpoint, would I be better off upgrading to a denon (have a 2312 currently... I think) with pre outs or just buying a dedicated pre amp? I've been happy with my denon so I haven't looked around yet. But, I'm getting a new room (15 by 30) to play with so I'm getting all kinds of bad ideas!
