Congrats again.

And again for the record, I have no doubt that the Audyssey system had a huge effect, and that there will exist very noticeable differences between it and other systems - like Trinnov. Other features (and proprietary surround modes etc.) can and will alter the sound considerably and very noticeably as well. However my comment that the basic sound properties (noise, distortion, and frequency response) should be identically-excellent for any properly-designed pre/pro, across all price points, stands.
