Actually, both answers aren't correct for my listening tastes. I voted for the 50/50 split but I don't listen to any 2-channel music. All my music is enjoyed thru Dolby Pro Logic 2x w/o the center channel. It's 2-channel with a 3 channel background and for me, it doesn't get any better than that. I'll also add that my main source is my HTPC, the heart of my home theater for both audio/video.
