In my system, Hotel California sounds spectacular. The guitars are very prominent in the left and right main speakers and they sound incredible. Guitars from the surrounds? It sounds like you may have a set-up issue.

This probably isn't helpful...but I wanted to chime in because what you are hearing is the opposite of what I'm hearing. As the previous poster stated, I use this disc, and Hotel California in particular, as demo material.
