Hi, it's been quite awhile since I last posted here, but I could use some help / insight. I apologize for the long post, but I wanted to give a complete account. I recently picked up a Yamaha RX-A2000 to replace a deceased HK AVR-7200 (leaking capacitors
). Connected everything, ran YPAO, popped in an SACD, and everything sounded great. Of course, SACD uses the player's sound processing, not the receiver's.
So, I switched to a movie, and the results weren't merely disappointing, they were completely unacceptable. There was no bass (I subsequently saw that YPAO had adjusted the subwoofer to be -6!), the surrounds were barely audible, and the center channel sounded hollow. Only the mains sounded reasonable, but the soundstage was still very narrow. (To emphasize, the only change in the system was the receiver; DVD/Universal Player and speakers were the same. I have a 5.1 speaker setup--3 Sapphire XL's across the front, and 2 Emeralds for the surround.)
I wondered if my receiver was defective, so I reset my receiver to factory defaults, pulled out my trusty Radio Shack SPL meter and decided to dial in the settings manually, first setting the speaker distances, then setting all speakers set to Small with an 80 hz subwoofer crossover (which I think is what I had used with the HK receiver), setting the PEQ to 'Through' (i.e. disabling the equalizer), then playing the test tones and making adjustments until all 5 speakers were at or around the same level (and the sub was in the ballpark). After manually setting up the speakers, things were MUCH better. The sound stage was as wide as I remembered it with the HK, dialog through the center channel sounded much more natural, and the surrounds and subwoofer were now properly integrated.
Before I went with Yamaha, I had read that people generally liked the Yamaha YPAO auto setup routine, comparing it favorably to the Audyssey system that Denon and others use. Most of the posts that I read suggested starting with YPAO and tweaking the settings from there. Yet my experience with YPAO was decidedly negative--so much so that I ended up disabling it. So, is something wrong with my receiver's YPAO processing (in which case I'd want to swap the unit out while I'm still allowed to by the store), or was it user error? Or neither, and YPAO is dodgier than I was led to believe?
Thanks for your help,
