My understanding is that most of the improvements in the higher grades of Audyssey do a lot to improve the sound coming from the subwoofer, so comparing it to YPAO might not be appropriate.
Unfortunately, like MCACC, Yamaha's YPAO does not EQ the subwoofer at all, or any frequency below about 34Hz. Given what a big deal Audyssey (the company) makes about the need to EQ the subwoofer, I'm surprised that neither Pioneer nor Yamaha has done anything to compete in that range.
It's also surprising that the two new high-end Cambridge receivers have only Audyssey 2EQ. Lots of people are scratching their heads over that decision. This is their first foray into room EQ, though, which might help to explain it.
