Dave - I also have a Denon 2200, but using it with a 1070. I've only had my 1070 for a week so have not tried my SACD's yet. Just now I put one in to try it out (Dark Side Of The Moon). All the speakers work on mine when I pushed the 7.1 button on the remote. I notice on the 2200 there are two pairs of outputs for the front speakers LF1 RF1 / LF2 RF2. I happen to be using LF1 RF1, not sure if it matters. Also in the SACD setup, make sure all settings are correct (multi-ch, etc...). You have probably done all this, but just incase. And like Gonk said, make sure the FL and FR are connected to the L R on the bottom row of the 970.
Oh, you know what, I just noticed this post is a month old, you probably have it solved, if so what was it?
