Last night I decided to run the Audyssey MultiEQ automated setup (against my dealer's advice I might add) just to see how good this thing really is. I let it over ride my manual settings.
This is the first receiver I've had with Audyssey but I can say I'll not use it again. I silenced my entire house (A/C, running water, everything) and let Audyssey go with 3 measuring positions per the manual's instructions.
The first thing I noticed was the distance for each speaker was wildly off the mark. The sub was 19 feet off
! In addition, it disabled the crossovers and set all my speakers to Full Band. I was previously crossing over at 70 Hz.
Ok - So I'm not looking forward to this but I'll give it a try. Well, I popped in Wall-E which has a lot of good spatial effects. Those were "OK." They weren't as on target as when I manually set the speakers but they were 'fair.' The sub was effectively neutered.
Even when Eve's rocket landed it bairly whimpered let alone rumble. The towers were attempting to pick up the slack but it just wasn't the same.
IMHO - If someone relied exclusively on Audyssey as gospel they would be very dissapointed with how things sound. Do yourself a huge favor and hit the microphone with a hammer as soon as you see it so you aren't tempted to use it.
The only slack I'll cut Audyssey is that it can handle up to 7 or 8 measuring positions and I only used 3. So maybe it would do better with more positions but I'm not holding my breath.
