I'm considering the Auro 3D format for my HT. The A6A has 9.2 and A8A has 11.2. My question is which if either will allow me to add the center height (VOG) channel or Center Height?\n\nUsing either of the above AVRs, my setup will be 7 pre-out amplified channels controlling (3 main\/2 front heights\/2 rears); 4 surrounds driven my AVR internal amps (2 side surrounds\/2 rear heights) and 2 subs. \n\nI've read that I can use one of the sub outputs to drive the VOG\/CH channel, but that will take away one of my subs (a mini dsp is an option but I've heard it causes popping in speakers). \n\nLooking for options and advice from someone who has similar setup and\/or experience with these AVRs?\n\nPic below without the FWL\/FWR.
