First impressions at comparing MCACC with Audyssey.

MCACC was a one shot setup. The only thing I had to adjust afterwards is setting Mains and Center to small. That's all.

Audyssey was a 6 time setup with mic, but short, not long like MCACC. I had to set cross over in 2 places. I had to readjust the level of center channel by about +4db. I could no longer use a max volume setting because I'll be using settings higher than the available max.

With MCACC, I'd watch TV at about -10. With Audyssey, it's at about -7 for the same volume level.
