I am currently running N804s through a MF A300cr power amp (225 wpc). I had upgraded from a Rotel 1070. The Rotel was grainy and never quite sounded right. The MF is an incredible dual-mono beast, and sounds very musical. Also, B&Ws like lots of current, so I can't see why you'd trade that for some "modern" inputs. Your speakers may not sound as good as they do with the MF. Even though the MF is older, I would keep it.
