Other than maybe finding the optimal frequency to match a subwoofer to its main speakers, what does YPAO and other parametric optimizers do that the average user couldn't? Speaker output level, delay, etc...Most people probably have a good grasp on these already, or just don't care. Is there someting else? Thanks.
Yes Kexo, there IS more to it than that. I must disagree with Wasch_24 when he says that "for an experienced user, it's really a non-issue" ... far from it. If all it did was to set speaker levels and delays, he'd be right. But, and this is the most important factor, it also tailors the frequency response of each speaker to maximize the accuracy of the soundfield, due to room resonances and standing waves, etc. which can seriously degrade the final sound experienced by the listener.

But the bottom line here is that regardless of what other receiver mfgs. do or don't about including such a feature as this, Yamaha still represents the best value(s) in receivers today ... bar none. I base this statement on having worked on this gear for more than 50 years. Today, I wouldn't consider buying ANY other brand for my own use.
