I agree that there are many "newly enlightened" vinyl "experts" (i.e. Drips under Pressure) on the High End scene.
The old die hard pros already have purchased many records, built collections, and knew record care and turntable/arm setup since the 70's.
This thread topic preaches to the choir!
Today you have to learn optimal turntable/arm setup on your own, as it a "lost" art. No store can do that.
After 1990 many records were reissues of questionable quality, due to the "lost art" of record manufacturing, and aged or lost master tapes.
Today there are almost no classical reissues. Too many popular reissues that every hard core collector already has. And too much digital sourced vinyl. Although much Jazz has been reissued since.
New records are now pressed in 5000 unit lots for the world market.
Too many $50 45 RPM records that require getting up to flip the record every 12 minutes.
Used record stores are "picked clean", with the good vinyl going to the clerk or on Ebay.
The days of "plentiful choice" of near mint records at cheap prices ended in the early 90's.
It is very hard to build a great 2000 Lp collection now, for those starting out.
If you now have a big lifetime collection of minty Lp's rejoice! You are set! Great turntables, arms and MC cartridges are better than ever.
Will this last? I do not know, or care. I am set till I pass!
