Channel levels are not related to EQ calibration, so no, they did not change. But S-Wave and EQ change depending on delay time. I did auto mcaac custom....keep sp settings......and MCAAC checks your room for reverb and selects the appropriate delay time. I think. I know if you run straight auto mcaac then the delay is 120-160ms (or something close to that). But the manual hints that auto mcaac custom....keep sp settings....will check reverb of room and set delay. But I cannot be sure.
Again...what I did find (in my room at least) is that the lower the delay time.....the less attenuation of the lower frequencies. The longer delay time.....the greater the attenuation of the lower frewuencies. 125 hz most notably. There were some other changes throughout the frequency range as well. I liked 30-50ms. I have a reverby room, so I want attenuation....in the RIGHT PLACES. And that is precisely what MCAAC is great at according to my ears anyway.
I recommend running Auto MCAAC, then running Auto MCAAc Custom Keep SP settings. Then running advanced eq using 30-50ms and save all three correction curves (symmetry, fr align, all ch adjust)to three different presets, then compare. But I liked symmetry the best. That and front align was close, but there was just something slight smoother and more detailed in symmetry for me.
