Thanks gonk. Your guide means so far I managed to stumble through everything on my own! I do have a question you do not address.

Until now I have used the 990's full bass management for all sources with speakers set to small and crossed over. Now with the BDP-83 I have been trying out the stereo analog output from the BDP-83 to the 990's CD input and setting it to analog input and BYPASS when playing CDs and 2-channel programs on DVD-A and SACD. As you know if the sub is turned on, both the front speakers and the sub get full range signals when the 990 is set to BYPASS. This "double bass" is clearly noticeable when I switch to the digital coax line from the BDP-83 which does all the bass management properly.

When the 990 is set to BYPASS do the front and sub channel calibration levels in the 990 set-up have any effect or are those bypassed too? What about the 990's 2-ch sub trim in BYPASS?
