Dave,
Thanks for the detailed description. One thing I want to add is that my 800's sounded kind of edgy and analytical for the first 100-200 hours of playing. Maybe the MS 5's you've listened to were brand new out of the box (my guess). This is sometimes the issue with demoes. The speakers have not been broken in (sometimes on purpose)and that gives listeners the totally wrong impression of how they really sound.
