I can't explain it in rational terms, much less measurements, but I do consistently find that a well recorded record, played through a good, entirely analog system has some sort of "life" that I really like. I'm not an analog zealot nor a cd-phobe but I do think that CDs were too early in the evolution of digital sound to exploit the full possibilities of digital (SACDs really DO perform). Whenever I hear the same thing on a CD vs vinyl, I find myself kind of startling and saying,,the vinyl really sounds good. It's immeasurably fussier to set up and maintain and records are fragile, but I guess that's part of the mystique.
