Hi--
I just got a Denon 1930CI and the only way I could get the SACD part to work was through the 7.1 Direct inputs (I have a 5.1 speaker setup). I use the optical ports for all other audio inputs.

The audio settings in the 7.1 Direct menu are disabled (I guess when they say Direct means direct after all), so I don't know what type of levels are being produced or how they can be adjusted, other than to say it sounds great as is for now.

There's also level, delay, and cutoff settings (all my speakers are set to small) on the DVD side, and for some reason, the cal test signal only produces audio from the left and right front speakers (no center, rears, or sub). But I can change these settings here that function just fine in actual use.

But after only spending a little time, I'm amazed at the difference over the old Sony 5-disc changer in both video and audio quality--it's like a new toy altogether. Now to get all the settings into the remote, and dig a little deeper to figure out how to get the best settings done.
