I had been using a Denon 3801 for a combo. I have a Behringer EP2500 for my subs. I tried the Behringer with the Denon. It was better, but not by a landslide. When I setup the Sherwood with the Behringer, it was a whole new world. Could hear many things I had never heard on CD before. Some things were a tad bright, but I think it was just that the Sherwood was passing through the true nature of the recording. If I had walked into a room blindfolded and you had stuck me on the couch and played Bob Seagers "Turn the Page", I would have sworn he was on a stage in front of me. I could hear him breathing on the mic, hear the crowd in the room, everything very detailed and clear. My wife was equally impressed. I am so glad I upgraded from a receiver to a pre. 100% difference in quality. Hope it helps.
