In one of James Michener's many really big novels he writes about tech specialists who could work anywhere in the world, tended to obsess about and own fantastic "stereo" systems, but seemed to only buy "Best Of" compilation LPs.

One thing I've noticed in places like thrift stores is that it is hard to locate amplifiers or receivers with a phono amplifier circuit - most likely because all the relatively recent ones require a pre-amplifier to play LPs.
