kcb & sh: here are my questions:

1.) what happens to the signal of a stereo cd when played in 6 ch. bypass? (sound comes through all 6 channels and i have no clue how it's routed or what that does to the test)

2.) kcb, fortunately, you can get the signal to play through only L+R+sub if you are in stereo mode before engaging 6 ch bypass (though some view it as a glitch). which was the case when you tested for phase in 6 ch bypass?

3.) soundhound, did you also see the approx. 180 shift in phase that kcb observed with your test disc?

4.) kcb, did twaeking the phase on your sub essentially correct the phase problem?

i appreciate any input on this subject. i think it's a very important discovery and can lead to getting the best out of the 950 in all listening modes. if the sub is out of phase with the mains, the rs spl meter calib will result in a terribly bad calibration.
