tempdlp,
Good catch.
Stereo, Bypass, and Upsample ALL have the same volume and sound beautiful!
No wonder I was griping last week. This 990 is 10x better now. Excellent sound.

In case you miss the edit I put in my post above, I will put it here too:
Make sure you set Tone Defeat on. Per Outlaw support, setting it to ON bypasses the DSP, when playing a CD through a digital source. In addition, I think he said there is a bug that messes up Bypass mode with tone defeat=off (even if Bass and Treble are set to 0) with a digital source -- that will be fixed in the upcoming firmware.
