I will add that a good preamp makes all the difference in the world. I was running my Adcom with my Yamaha receiver before upgrading to a Nuforce preamp and I will say that it does make a difference so any amp you go with will improve the sound but a great preamp is the heart of the system that most people overlook as a sound quality changer but it does effect the sound quality in a big way and it makes sense for it to since the volume control, preamp circuits, and inputs all go through this unit to be switched to what you are wanting to listen to and that means that it does a lot of work and needs to be quality built to get the most out or your amp and speakers. so do dismiss that as a upgrade once you settle on a good amp.
