I have this preamp connected to some decent power (Bryston) and love the way it sounds. But if I could do things over again, I would have gotten the RC-850 instead as it has inputs for both an MC and MM phono. I don't know why Rotel didn't have these in this newer version??? That's why it only gets a 4. I had to get a separate phono pre in order to get it to work as part of my system. Other then that, its a pretty good preamp for the money.
