James Cruz is a Grammy award winning mastering engineer who blogs about such things, and he has written an article making the controversial claim that vinyl is inferior to CDs in that the former has far more limitations. The summary is that in any analogue format, the medium itself will react differently to certain situations, right down to the fact that the inner region of a record handles sibilants far differently than the outer. Interesting read from an amazing pair of ears.
The moral of the article is a lesson all audiophiles really need to learn, which is that most things don’t sound better or worse, just different. Of course, we’re all just listening to MP3s at 320 now, so maybe it’s a deck chairs/titanic sorta thing.
