Obviously the lack of subwoofer eq and global crossover is a minus for MCACC. Luckily for me, neither matter that much. More
crossover choices than 50, 80, 100, etc. would be nice though. I also really like the 6 presets the remember eq and speaker volume settings. Pioneers Advanced MCACC also offers many adjustments and tweaks as well as other things like Dialog Enchancement and Optimal Surround which can be usefull. And you can set speaker sizes, etc before
running the program if you would like rather than changing them afterwords.
Audyssey seems to improve the sound quality a bit better than MCACC to me and I guess newer versions also have several presets? I've had several Elites over the last few years, a couple of Marantz and an Integra or three. My brother has a Denon To me, Audyssey, with it's Dynamic EQ/Volume, are better for over-all sound quality but MCACC can have it's advantages. The only way to know for sure which is best for someone is to compare them side-by-side. I also find Pioneer, Onkyo and H/K receivers much easier to use then D/M but that's just me.
I've compared MCACC's Advanced (Elite 23vsx) to Audyssey MultEQ (Marantz 5005) using both multiple mic positions on Audyssey and a single position like MCACC. The EQ settings between the two were vastly different. Which one's correct? I don't know either.
The very best sound I've ever had was from an H/K 435. I ran EZSet/EQ several times (they don't always sound the same as they did before) until one time it sounded fantastic! Got a bit cocky and ran it again thinking it could do even better maybe? Nope. Never sounded that good again
. Oh well.
