I think it is very feasible if the two integrateds are the same. If not, tweaking would be required, but it would work. You could also try it vertically by by using one integrated per speaker. If your image is centered, I would say the two integrteds are playing at the same level.
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.
