As far as "wear and tear" goes, one day, while playing a vinyl record, look up close to where the stylus makes contact with the vinyl grooves. Look closely. Or even get a magnifying glass and see what is actually happening. It is organic and physical. Nothing wrong with that. And many records play very well over many many uses. But it is friction and there is a wearing away over time. Same with tape. Don't be misled. Yet, having said that, it makes it even better to "feel" the audio from the physical grooves and hear the result!!!! I agree about that certain "grungy-ness" about some LPs/45's, that is lost when it comes to be transferred to CD. I think that is because of the digital aspect involved. That's why analog sounds better. I'm not an audiophile expert, though. I just know what I hear and use common sense. The Time Fades Away album just is phenomenal in it's roughness, sloppiness, real emotion-ness.
