Hi Casey01,
Absolutely, and we often recommend that option if a customer has an AV receiver that he wants to keep and use as a preamp-processor. Simply adding a 2-channel power amp to the left and right main channels to drive the 4-ohm M80s works very well, using the receiver's internal amplifiers to drive the other three or five channels.
Of course it costs more going that route but it will also buy you a great deal more power for the main channels than most AV receivers are able to produce when they're running in a 5.1-channel mode.
Regards,
Alan
