Need some advice on buying a new AV amp/receiver. I have just purchased a Panasonic DVD Recorder DMRE-50. I want a new amp to take advantage of DD,DTS etc. I am considering a Yamaha RXV640. My current set up is an old Yamaha Pro logic amp & Bose speakers. The problem-my Bose satelite speakers run off the sub. It says in the instructions I cannot connect the sats direct to to the amp. Therefore I can't see how I can set up a proper 5.1 system with my Bose speakers. If I leave the sub connection out and connect the two sats (which run through the sub) to the front left & right channels will I get any bass? As long as I get bass I'm not bothered about a proper 5.1 set up. Any suggestions/ ways round this.
