Having a high end CD player is like having the best standard definition tv monitor, 525 lines. But having a turntable is like having a 16mm projector. If the 16mm film print material is in good condition you will have very little scratch and its resolution can approach 1080 lines (HD resolution) - if the image is captured well and everything is set up correctly. (35mm film can have maximum of 4k resolution, which is like having audio master-tape) That's the analogy I've been using.
CD player or redbook digital is convenient and consistent but it's limited by its redbook standard, just like SD TV is limited by its inherent resolution. But 16mm projector is a pain in the butt, you get the picture.
