Having changed from a normal stereo hi fi set up (NAD 350 amp) to home cinema (Yamaha DSP AX640SE) I thought I would go against my beliefs and to save space use just my surround amp for movies and for music. However, I just can't put up with the drop in quality of stereo music so thought I would put back into the system my NAD amp. Following advice on several websites i've connecting the two amps together using the pre-outs on the AV amp to the Ins on the NAD so that powers the two front speakers for stereo and surround sound and have CD / Tuner / Turntable fed into the NAD. Now the problem, surround sound works perfectly but stereo sound results in no output whatsoever! I'm sure i've done something obviously wrong (bearing in mind I set about this after a night in the pub!) but am not sure what. Can anyone give any details on exactly what connects to what so i can regain music playback through the NAD while being integrated into a surround setup? I cannot see what can be causing this and really can't put up with the rubbish stereo playback much longer. Cheers in advance.
