Linked review of the Yamaha RX-V2400: interesting stuff about the YPAO
Audioholics posted their full review of the RX-V2400 and it has an excellent overview of the YPAO room acoustic calibration feature, and what it does and does NOT do. Some interesting points on the YPAO -- it is accurate for automatically setting the speaker levels and equalizing each of the speaker outputs.
However, disappointingly I read that the YPAO does make any adjustments for the subwoofer output, nor any frequencies below 63 Hz. IMO, the low frequencies are where the parametric EQ is needed the most, and having this kind of adjustment done automatically could have propelled the YPAO-equipped Yamahas far ahead of the pack. Also, the parametric EQ center points and bandwidths cannot be manually adjusted. As such I would regard the YPAO as a step in the right direction, but not quite there yet. In any case, you would still need to use an outboard parametric EQ in conjunction with any subwoofer, and do the measurements manually if you want to maximize your bass response.
In other areas, it sounds like Yamaha also made some good improvements over the previous model. The link to the review is below.

Oh, You mean the one I post back abjout a week or two ago? :)
I guess everybody missed that post. I was very curious to see feedback from the YPAO tests. HomeTheatre Mag did a review on the RXV2400 as well and had similar results. OI thought HT review was week as it barely touched the sound of the receiver. They hung up on the feature part without dwelving into the sound. Oh well.
