I just can't get past the 3D imaging and visceral sense of space that comes from genuine, quality stereo recordings. As lovely as a mono recording might be when it comes to performance and timbre, it just ain't enough for this dude. Right now, for example, I'm listening to an absolutely wonderful recording of Mozart's Marriage of Figaro via Primephonic. The vocalists are wandering around the stage -- left & right and front to back. An unalloyed delight.
