I'm looking for a midrange preamp to go with my Rotel RB980BX power amp. I am currently using a Rotel RSP960AX preamp/processor which in truth sounds very good. It has a full bodied sound with a warm midrange and smooth treble. The bass is also full, but lacks a little in definition. Since the Rotel is not a true preamp, but a preamp/surround sound processor, I was wondering if I would be better served by a dedicated preamp to improve sound quality. Any suggestions?
