It's the whole volume-control thing. Maybe stack the two integrateds on top of each other, and put a nice postal-sized rubber-band (or two) between the two volume knobs? It'd be nice if the knobs were the same diameter . . . :)
Using 2 integrateds to bi-amp?
Maybe this is a really dumb idea (if yes, please tell me why). Would it be possible to connect 2 integrated amps by Y connectors to a single source (e.g., TT or CDP)then use 1 to drive the L & R tweeters and the other to drive the L & R woofers of a 2 way speaker system? I have two integrated amps but don't have $ to go mono-blocks + pre-amp.
