gonk: that idea has crossed my mind several times. However, right now, my attention has been focused on the new Samsung TVs. Initial reports have been rather promising, but there may still be issues with lip sync/ video lag, and 5.1 transmission from the optical output port. These could be show stoppers for this TV.

After I figure out which HD TV I am going to get, then I will focus on the audio upgrade.

The comments here have been helpful.
