1. The first thing I would do is go into Audio:Audyssey and verify Dynamic EQ is on.
2. The next thing I would do is try the various settings for MultEQ. Reference rolls off the high frequencies while Off turns off Audyssey.
3. If none of this helps look at the Audyessy settings file you saved with the app. Open it and turn off midrange compensation for each speaker. Then load the settings file back to the receiver.
4. You could adjust the EQ with the Audyssey app but the Reference level rolls off the highs automatically so its doubtful that would be needed.
My guess is one of these settings will land you in a sweet spot to your ears. Turning on Dynamic EQ can make a difference by itself. I would leave Dynamic Volume off.
The app will show before and after graphs but they tend to be less accurate than if you analyzed the output with REW. My guess is one of the items in 1-3 above will make the adjustment you desire.
