Anquisitum -
It sounds like we have identical tastes in churches! I think there are some Episcopal cathedrals in large cities that come close to what you are describing. Unfortunately, for me, none of them are where I live.
My favorite is Grace Cathedral in San Francisco - they have a wonderful Web site.

I do enjoy downloading progressive sermons to my iPod, though, and I can imagine the gorgeous cathedrals since I can't often visit them in person.
