If there is anything that I feel is different with 7.1.3 it is related to the sound stage, the center image seems more forward to me. It's the one thing I feel I can truelly remember as I spend so much time concentrating on it. I listen to music with vocals 95% of the time.
I don't trust my ears and brain to tell me if it's slightly brighter, warmer, more musical etc etc. Human hearing can change day to day with diet and stress. I need to be able to switch back and forth within 30 seconds to get picky on these things. That just isn't possible with a 10 minute firmware upgrade for me anyway.
How that center image moved forward might be related to mids as others have mentioned.
Now I've stuck my neck out there.
