I have a Yamaha A5 which I use as a processor. It drives the centre and rears, but I use the pre-outs to connect to my main hi-fi amp, which then drives the front speakers. I don't have a sub, but it will be my next purchase. I know that it connects to the A5 using a phono lead, and that it will work fine for DVDs, but what about music? I could connect it inline using the high level inputs, but that would then interfere with the line level input when listening to a movie. Does anyone have a similar setup, and if so how have you connected your sub? If I have to use it for movies only I will, but if I can use it for music as well that would be great! I was thinking of a Yamaha YST320 or 800 sub, if that helps.
