Touche... But I would be playing with a preamp rather than a tube amp. Tube amps have the ... errmm.. the tube sound. The tube pre-amp is less so and just a little touch warm...which mean could be rolling off in certain frqouencies and a little noise and sparkle.
True...if it sounds better to you personally. But I thought music was always recorded with 1 or 2 mics in front. Unless the recording was made specifically recorded or digitized to use all available speakers hence it needed to have mics in all 5.1 6.1 or 7.2 locations. I like listening to music the way it was recorded.
