Yes, DVD-A and SACD require the multi-channel inputs. I have things pretty much "dialed in" now where movies and SACD/DVD-A are sounding great but haven't tried many formats other than dolby digital. For now I am using the 1070's bass management toggle set to digital which means the 1070 is handling bass management. Intially I had it set to bypass so that my Denon 3910 would do the BM but had some problems which requires further investigation.
