YPAO vs Audyssey

Audyssey is a much more sophisticated system that employs several digital FIR filters (Finite Impulse Response) of much finer resolution and in particular in the Bass where it counts the most!
And not only it applies those filters in the full Audio Frequency Range (from 10 Hz to 24 Khz in products that have at least Audyssey MultEQ, but also in the Time Domain to take into consideration the first reflections in your room, which are from your walls, ceiling and floor).

There are several threads here at Blu-ray Forum (one of them is a 'Sticky' by Big Daddy) which explain the 'inflections' of the Audyssey system.
Please refer to them, and see for yourself if you consider Audyssey to be a superior system with way more digital filters of much higher resolution.

For me, it definitively is! You don't need to be an expert to understand and to verify/confirm why!

This being said,m there will always be some compromises when using digital EQ in any system. And what might works great with Movies might no be as good with serious Music two-channel Stereo listening. YMMV

And there are other people that like to manually 'tweak' by themselves!

But there is no doubt in my mind that a system like Audyssey MultEQ XT32 is one if not the very best out there, among ARC from the Anthem Statement D2v/ARC1 pre/pro ($7,500), with it's combination of both FIR and IIR (Infinite Impulse Response) digital filters, better than the Parametric variety with separate 'Q' adjustment, but which works only in the Audio Frequency spectrum with very limited bands.
There is also TRINNOV, that works in the Frequency audio Range and Time Domain as well, but adds 3D Remapping with Horizontal and Vertical plane dimensions. And it also adds manual parameter adjustments as well separate target curves that you can select from its memory. It also has a Center channel 'Lift'. Plus you can change the position of any speakers in your room!
But TRINNOV is not popular YET because of only one consumer product from the Sherwood Newcastle AV receiver, the R-972 which have few flaws in the implementation of its HDMI connections plus others...
And we don't know just yet about their newer receiver, the R-876.

It is all a question of intelligent implementation of these various systems and their true efficiency.
And Audyssey has a long proven experience so far, and for me as well several other people it works good enough to be the top gun in our list!
>>> Just check the "Official Audyssey Thread" over at AVS Forum! That should be your very best indicator with the HUGE amount od posts and viewings!

One last thing: Audyssey takes 6, 8, or up to 32 mic positioning measurements in your room, to give you a much more accurate reading of your overall room acoustics! It is from a much larger and overall balanced area where more people could enjoy different seating positions! And not just one person!
Room acoustics are not from only one position in your room, but from several more!
A Parametric Equalizer only works for only ONE SINGLE position! And you need much more than only seven, nine, ten, or fifteen bands EQ!
The more capable separate ones (Rane, Soundcraftsmen, mini-DSP, Anti-mode, Behringer, etc.) use thirty bands or so, plus some specifically for the lower bass frequencies (Subwoofer).

It is in the Bass, below about 300 or 250 Hz that digital EQs are most useful!
A separate Subwoofer EQ is a very good thing (essential) to have the very Best Balance of Bass in your room! And you also need a good mic, like an ECM8000 or similar, with a Phantom Power (pre/amp), and also you need to take measurements in your computer from a system like REW equalization & measurement.

* There are tons of information at "The Shack" and several other Audio Forums on REW. And there are other systems as well, free programs from your PC.

Hope this helps a bit to align you in the right direction, and with a basic and important set of information.

Cheers,

Bob, thank you for your input You bring up that a separate subwoofer Eq being essential. Is this what the Audyssey Sub EQ HT does? I see that this is only included with MulyEQ-XT32. Is this something that is used separately (separate setting)or is it automatically implemented within Audyssey?
