Did you ever consider contacting PS Audio: Since you own their premiere product, I am sure Paul & his customer service dept would be most happy to help you.
I am not sure how long you have owned the 802D1’s, but it could be you just don’t like them and the issue is not fixable, PS Audio and B&W may not be a good match. your room maybe overly bright. Like everything in audio, there are too many variables.
