I found the MCACC does a wonderful job of calibration. Even better if you go to the custom, and allow it sample 3 positions for phase alignment. I also prefer the independent EQing for each channel rather than the symmetrical pairs. If you need help with getting it to run through that mode let me know, I'll give you a step-by-step when I get home.
I did the calibration when I bought it but now I'm running with my own custom EQing. I may have made it worse.. who knows..
I'm not aware of the custom three positions sampling.. will investigate that.. thanks
