Are we talking about my nuts or acoustical studio foam?

I haven't experienced it (at least the foam comments anyway)

Do you have any low end absobtion? (auralex doesn't make any) That would be the problem with the lack of sparkle, you killed the highs without killing the lows as well.

Definitely. The absorbers are broadband, and along with the lows went the highs. Had to put some of the highs back in --- Much easier than getting the lows under control.
