How successful is the equalization, particularly at low frequencies and is it more or less successful in the same environment than something else the user had experienced before -- that kind of thing.
There is virtually no information available on how people think Sony's top of the line EQ performs compared to others, so I've been genuinely curious for a while. Users post about other EQs, but none of the Sony owners seem to do so.
I've never owned an AVR like Denon (uses Audyssey) nor a Yamaha, so I can only speak of my environment with the Sony. I'm also not an expert on this stuff but I can only tell you what my ears like. I think the Sony does an outstanding job. All my speakers (9.1 set up with front heights) are sonicly matched and after the room calibration is done the sound stage sounds amazing. I use Sony's HD-D.C.S Theater setting as I primarily use the AVR for movies. For music, I'm not a purist, so I use PLIIz Height which sounds great.
I do have to tweak the LFE volume as the calibrated setting can over drive the sub depending on the movie. I have a few clips from several movies that I've used that really have high impact LFE and I use those for reference that allowed me to set it properly.
One other thing is that the calibration will configure the levels based on the speaker size (frequencies determine this) so if the surrounds are determined to be large, then the levels are set based on that. I mention this because if the speaker size is changed manually, bass steering will occur which will then require further adjustment to the sub as bass from those speakers will be sent to the sub and fonts based on the crossover frequency set for the small size. Once I figured all this stuff out, I'm extremely happy with the results. I previously had the STR-DA5500ES and wasn't sure if the 5800 was going to add all that much, but I was pleasantly surprised at the improvement in the sound presentation which sounded even fuller and better defined. I later added the 2 front heights and they really add even more to the depth and sound stage.
Any way, all this is obviously subjective, but I hope it helps in some small way.
BTW, one thing I thought Sony really dropped the ball on is the fact that I can't save my AVR settings to USB or upload/download/modify through some utility. The STR-DA5500ES had the Sony ES Utility which allowed me to store all the settings so I can restore them quickly if something happened, but with the 5800, if something changes or you lose the settings, then you pretty much have to start from scratch.
