I don't even want to tell you guys how many dumb things I did today while trying to integrate my tube preamp into the HT mix, but I finally
got it figured out. May I remind you that I scored dismally low on the mechanical aptitude test, and today was a reminder why. . .
In any case, good news, I ran the test tones through the analog inputs and everything is fine. Checked both DD and DTS and both come out even across all speakers. I don't know why I was getting different results before. . .well, read the above paragraph.
