Looking to run 7.1.4 AND Zone 2 with a Marantz SR7010 (9 channels of amplification, 11 channels of processing), and I was wondering if it is OK to run not one, but TWO external amps with this unit - one amp to run Zone 2 from the pre-amp outs, and one amp to run a pair of my up-firing Atmos add-on speakers. I realize this may be a stupid question, but whatever geniuses they have answering tech support emails over there at Marantz didn't have a clue what I was talking about. Can somewhere here please advise? It would be much appreciated. Thank you!
