I was thinking about keeping the 7125 as a back/rear amp to power all the rear/surround speakers from a signal from the AVP through the "OWA-7". The wireless part is the 7125 getting its input from the "OWA-7". I would have to split the signal to several pairs of speakers to use all twelve at the same time, unless I fed the 990 from the Onkyo 886 through a digital signal and used both processors at the same time. I wonder if the OPPO will allow both its HDMI and Component digital outputs to be used at the same time. Then I could feed each AVP its own audio signal and tune them separately. Could be a killer setup for Movies. I could bi-amp the mains up front and still have the center off the 7500. That would leave the Sides, Rears and Height channels for the 7125 with a spare channel. Maybe I could drive a butt kicker with the extra channel.
