It does sound a bit depressing, and some of it is true and some of it is false.
He's right about proper (even paying a pro to do it) setup & alignment, turntable isolation bases, and I'll add that cartridge-to-tonearm matching is equally important, especially when dealing with vintage equipment and new production cartridges.
I've heard plenty of excellent (and some spectacular) sounding half-speed masters, and 180 and 200g "heavy" pressings.
I was indoctrinated on the ratio of cartridge-to-turntable spending until a HiFi shop owner sold me a Rega Planar 3 back in the 90s. The turntable without cartridge was $500 at the time. He convinced me to spend $500 on a cartridge, telling me that it was a good match for the deck and would sound way better than the $150 Goldring I was considering.
THAT was the best move I could have made as the combination was excellent. Mostly, I think it was due to the quality of the RB300 tonearm, which, in my opinion, turned out to be better than some arms costing many times more.
