YPAO is a decent, but not entirely great feature. You can do the same work all by yourself with a radio shack spl meter. YPAO is automatic, but it seems to not do a really good job with the subwoofer (on an RX-V2500, at least).
The main advanatge to the similarly-priced Yamahas is the large number of available movie settings.
I disagree, the YPAO is easily one of my favorite features.
And you cannot easily replicate its results with just a RS meter. Remember that the advanced versions of YPAO adjusts both the center frequency and bandwidth of the adjustment on the Parametric EQ....Without some kind of RTA software, it is difficult and time consuming to replicate its results manually. It could save you hours of calibration time just to get the same result.
YPAO does not work with subwoofers because it wasn't designed to. Because subwoofer response is heavily dependent on multiple listening positions and placement, one should do that manually anyway.
If Yamaha didn't offer YPAO, I would have bought a different brand like NAD.
