I need help with connecting the following: Legacy Stereo equipment: Sansui Int Amp AU-g-99X Pioneer R-to-R RT-707 Sony Stereo cd Turntable mmf (not supported by A/V Recv'r) Using A/V Recv'r NAD T743 w/5.1 Complicating problem is I want to use Bose 901/s for L-R front speakers w/equilizer issue. (Mirage Omnistats for rear and will later add Subwoofer.) I think I need to reconnect legacy stuff to Sansui amp and connect amp to A/V but now sure how. A/V preamp out to what? Any help appreciated.
