They are going back to vinyl because it has been shown (with the right equipment) to have superior sound quality over CD or any digital means of recording. It has nothing to do with being a purist.
I have the right equipment ( Bergmann Audio Sleipner turntable/ Yamaha RX-A3010 9.2 Channel Receiver/ Bower & Wilkins 800 Series Diamond Speakers ) and I can tell you now that some LP's may be good but not as good as well produced cds and that's comparing with quadraphonic albums, straight off the bat cd's don't produce static which is quite obvious when listening to LP's.
I think we've gone on about this for long enough now and need to get back to the funnies
