That reflects both the inherent qualities and character of analog sound, but also the fact that record replay has significantly upped its game in the face of ever-increasing competition from high-res digital sources. These days, serious record collectors and listeners wanting the best possible sound will seek out rare original pressings, appreciate the virtues of mono (as opposed to many stereo) releases and purchase their discs, new and used, from all over the world.

Likewise, the once simple process of playing those discs can achieve levels of sophistication and record-by-record optimization we never dreamed of, back when the vinyl LP was the only high-quality format.
