Well she came today. After I got it all hooked up I threw in some cd's. Talk about power, this thing makes my 811 seem like a bose wave radio. I always used to listen to music on my 811 with the loudness on, otherwise it was just dull. This definately has more dynamics. Comparing the two right off the bat was no comparison, it beats the 811 in every which way like you wouldn't believe. For some reason though it didn't seem like it hit that low, then I realised the speaks were set to small, after I switched them to large, holy schnikes. With them set to small, it sounded like my 811 did set to large with the loudness on. I tried 7 channel stereo, and even with all channels driven, the mains went a lot louder and and had a hell of a lot more power than with the 811 running just 2 channel. I ran mcacc, and apparently I had a nasty hump of about 6 or so db. at about 63 hz, it quickly took care of that. It also set my sub at 11 feet, which it is in fact only about 6 feet from the listening position, I thought that was kinda odd. But after listening, it made a huge difference, the mains transition to the sub much better, and it doesn't sound bloated anymore, surprised the hell out of me. After flipping through a few dvd's, I noticed the surrounds all seem so seemless now compared to before. MCACC made a large improvement. I do have a couple questions though. 1. I am running monitor 7's front, cc-370 center, and mini monitors all the way around, do you think I should it to 8 ohms, or 6 ohms? I ran it at 8 ohms the whole time and even at extreme levels it never made a glitch. Also the dialog norm. When ever it receives a digital signal like when first starting up a movie, it says dialog norm. +4. Is there any way to change that? Or is that part of the mcacc? All in all. Very happy with it so far. Tonight I'm gonna mess around with mcacc pro, and see what that does.
