I just upgraded my system recently with a better receiver and better speakers. My system currently consists of an Onkyo TXSR800 receiver, Polk Speakers: RTi100's, Rti38's, CSi40, FXi30's, and an SVS 20-39PC +. I am thinking about going to separate amps and pre-pro. Any ideas on mid range stuff that can handle THX decoding, DTS, DD, etc. I could use my TXSR800 as a pre/pro. Probably would to start. Or would I be better off going to a dedicated pre/pro? How much would it cost me to get into separate amps? I would like something in the $1500-2500 price range if possible. I would need 7 channels since the PC+ has its own amp. Any recommendations on brands, pro's/con's, would be appreciated. Thanks.
