Currently running a 7.2.2 from a Marantz SR6013 and a stereo zone 2 through a Dayton amp to my patio. I just ordered a Marantz MM7025 to power the front towers. Looking through my manual, it seems I can run 2 channels through an external amp or all channels through an external amp. Although I don't see the settings for all channels, a note in the manual states running each channel through an external amp enhances sound quality.
I could wait and figure this out on my own, but I'd like to pull the system away from the wall once. Can I run my patio speakers through the Dayton, my front through the new Marantz amp and everything else from the Marantz 6013 internal amps? Or do I have to ditch the Dayton, run the patio through zone 2 speaker connections vice preamp, and then I can bring in the 7025 amp for the front?
I've attached the page from the manual mentioning an external amp.
