Well, first if you have the BDP-83 I wouldn't see any reason to hang on to the 970HD. Second, the BDP-83 can output SACD via HDMI just as well as it can output DVD-Audio, Dolby Digital, DTS, stereo and multichannel PCM, Dolby Digital Plus, TrueHD, DTS-HD High Resolution, and DTS-HD Master Audio. You will be able to connect the BDP-83 to the 997 via a single HDMI cable and use that for everything the player will play.
