But in some cases, high frequency distortion can present even worse problems, and that is where Audyssey is generally least effective. So, if you don't mind the suggestion, you might want to investigate some room treatments. A separate thread on that can often get you some free advice from industry professionals. I hope this suggestion is helpful.
I agree with Mike. I have heard that with sloped ceilings in which the two sides both are sloped to face each other and focus rather than diffuse (i.e., more or less concave, or triangular, rather than convex), carefully placed absorption is highly recommended. I saw a picture of a ceiling almost identical to yours, in which absorbing pads were placed on both sloped surfaces, spaced a bit apart, with a few more widely spaced ones down the high, flat center of the ceiling. Don't over absorb, though. It's a judgement call.
If you need to put back some of the liveness of the room after putting in all that absorption, could you put some diffusors on the back wall, behind you? Or even the wall in front of you, as well. That might make the room sound a bit larger, while the absorbing pads would cut down on any treble distortion.
Make one kind of change at a time, then give yourself a couple of weeks to listen.
Of course, every time you make any changes, you should re-run Audyssey. Your AVR or Pre/Pro should provide a way to store the old EQ, so you could go back, if necessary.
