I currently own the 803D. Sorry, I have no experience with Rotel amp, but I have found that you don't need heaps of power to drive the 803D to very high levels. This is based on my experience with using a pair of Marantz SM17SA (60W per channel) over a year. I briefly tried the Marantz SM11S1 which has an accurate power meter - 99% of my listening was less than 5W!!! The highest power that I noted was for the occassional rock - 45W! I have recently upgraded to a pair of Cambridge Audio 840W that are very smooth and detailed. They are rated at 200W per channel, but again it is the quality, not quantity that counts.
