Looking at buying the Marantz AV-10 but, had a question and wondering if someone could assist. I have a MiniDSP I just bought while my Denon X6700H is in the shop and I have 4 Klipsch 12" subwoofers in my home theater. I'm running a 9.4.4 setup. My question is; if I get the AV-10 with 4 independent subwoofer outs, do I need the MiniDSP? Or, should I send it back? My second option based on price is the Marantz 8805A and keep the MiniDSP. Any suggestions would be helpful, Thank you in advance.
