I agree with Viridian, the problem for me is availabilty. If you have a niche interest, where some of the great recordings may never have reached digital. Jazz I suppose , is the example that springs to mind.
For Me, it is Opera. Some of the great 50's to 70's recordings, never reached CD. The other thing to consider is cost. The great Jazz recordings can be expensive. You can pick up Opera vinyl very cheap. I bought Puccini's, the gear from the Golden West with Domingo, for £3 recently, unplayed and that is a Penguin stereo guide top, Rosette, performance. What more could you ask for?
