Audyssey and changing settings post calibration
I've read varying ideas and thoughts on the topic of this. My question is:
Does changing your speaker size, crossover, distance, and dB (using spl) AFTER Audyssey calibration, change the room correction? And if so, what is the point of running Audyssey at all?
I will be upgrading my AVR soon from the Onkyo NR787 to the Marantz SR6013. The main reason is for the room correction and calibration difference. My Onkyo uses AccuEQ, which in my opinion, is inferior to Audyssey. The new Marantz and Denon come with Audyssey XT32 plus the app that allows you to adjust the filters after calibration has ran. This seems more streamlined than my original plan of using REW, a UMIK-1 mic, and MiniDSP NanoAVR. Also, the DSP/REW solution isn't great for my 5.1.4 Atmos setup. I'd have to most like get (2) DSPs to handle my 9 mains and 1 sub. A Marantz or Denon in the $700-$900 range appears to be the best course of action.
But...as stated earlier. When I get the new AVR, should I set it up manually or with Audyssey? Doesn't changing all of those options after the calibration affect the sound that Audyssey just corrected for? For instance, let's focus on "distance". If Audyssey sets my left speaker at 10.2ft but it actually measures 11.7 to the main position, should I go in and change it to 11.7? My thinking hear is that during the Audyssey calibration, you place the mic in 8 positions. Also, the left speaker is in a corner with sound panels on the walls near it. Maybe that 10.2ft that Audyssey measured is "correcting" for materials, reflection, and multiple mic positions. Taking that same scenario further, wouldn't adjusting other settings post calibration have an affect on Audyssey EQ?
Please chime in with your thoughts and findings. My setup is 5.1.4 w/following equipment:
AVR: Onkyo NR787 (upgrading to Marantz SR6013)
L/C/R: Polk OWM5
LR/RR: Polk OWM5
Ceiling: Polk OWM3 (2 front / 2 rear)
Subwoofer: SVS PB-1000
