I don't listen to much classical, but I'd take the same attitude toward jazz. When someone out there starts producing lovingly mastered 5.1 recordings of Waltz For Debby, Tribute To Miles, Duke Ellington at Newport, etc., etc., mixed to put me in the middle of a wonderful (even if imaginary) ambient space and give me the feeling of being in the (a?) room during the performance, I'll start building my system. As long as the very short supply of 5.1 music recordings consists mostly of oddities that put the percussion player over my left shoulder or let the bass bounce around the room, I'll remain a 2-channel snob. In my view, 5.1, for music, is great potential unrealized.
