Sure, but I think the analogy is more appreciating the difference between the best orchestra playing a piece and a more average one. Or why one Bach composition is "better" than another one. I like classical well enough, but I wouldn't pay hundreds of dollars for good seats to hear a specific soloist in a specific theater.
