I currently have a Rotel RSDX-02 {5 x 80 watts into 8 ohms} reciever powering my B&W 705's. I want to get an amp to power the 705's; any suggestions? Also, I am going to get a matching HTM7 center channel. Any suggestions for a sub to round it out to a 3.1 system? Price range is between $300-$600 for the Amp and $300-$1000 for the sub... Happy New Year All.....
