One interesting side note, even though our listening environments, musical preferences and equipment are quite different, I believe that Mike L's, Joel's and my systems have all moved to a more similar sonic signature over time.
That is a key point. As systems, and individual components, improve, that is, they sound more like the real thing, does it not follow, that their respective sonic signatures tend to be less noticeable, and their overall sound, or lack of sound, seems to be more similar rather then different? I have found this with good tube amps and SS amps. The best ones sound more similar than different. Same with great analog and digital. There are still differences, but they are becoming less obvious. People have hinted in this thread when discussing Mike's system, that there is not much sonic signature left to the system or to the room, and that one is less conscious of the sound of the system, thus leaving him alone with the just the music. This seems to be Mike's goal, and that of many audiophiles/music lovers.
I was struck by Bonzo's comment about the WE speakers on the other side of Mike's room for a completely different sound. If that indeed would be the case, then either each speaker does something different exceptionally well, overwhelming its weaknesses, to remind the listener of real music, or, one of the speakers is more removed from the sound of the real thing.
