Jeffreybehr..."transported to the concert hall" is what a really good stereo system will do. Multichannel can do it somewhat better. However, multichannel can also do something that stereo can't...transport a small group of musicians, classical chamber group, jazz, or bluegrass, into your listening room. This makes perfect sense. It's the best "you are there" sound there is. It can also put you into the midst of a larger orchestra, but many folk, probably those who have not performed in an orchestra, find this annoying.
I think that center channel is very important, as it is the logical place to put a soloist. However, I agree that the center level varies a lot. I have violin concertos where, if I crank the volume up enough to really feel the orchestra, the violin is lounder than any real violin can play, and therefore is sonicly poor. It's like looking at your girlfriend's complexion under a magnifying glass!
Finally, I disclaim any status as a guru.
