I am not very familiar with YPAO (also ARC and other software) or it's equivalence to the Audyssey XT32 DUAL Subwoofer Equalization and Dynamic EQ.
I believe YPAO does more than adjusting those levels, but I have no idea how EFFECTIVE it is or how it actually sounds compared to Audyssey Sub EQ/ DEQ.
Everyone (Yamaha, Denon, Anthem, Pioneer, Emotiva, etc.) claims to have the best software.
For example, YPAO has a Dynamic Volume equivalent to the Audyssey Dynamic Volume and Dolby Volume Leveler found in Anthem AVRs. But I do not know if YPAO has an equivalent to Dynamic EQ. Dolby Volume Modeler in the Anthem AVR is "supposed" to be an equivalent to Audyssey DEQ, but I am not convinced. With the exception of Dolby TrueHD, I have very little faith in Dolby Labs in general.
I think the Onkyo 5007 AVR has both Dolby Volume + Audyssey DEQ. It would be interesting to compare Dolby Volume Modeler vs. Audyssey DEQ.
If Audyssey didn't have Subwoofer EQ and especially Dynamic EQ, I wouldn't care about Audyssey either. I would still be using Direct or Pure Direct modes like I've been doing the past 15+ years.
