I have paired my 750 with a Parasound HCA-1500A for a 6.1 setup.

While not quite at the level of performance and separation of good monoblocks the 1500 is a very good stereo amp and has matched very well with the 750. I use the 1500 to power the front channels and the 750 for the center, surrounds and rear surround. I am bi amping the center channel with two channels from the 750.
