Dear @lewm : My take in the MC 2000 issue is that was not through STPH JGH review who puts that cartridge in the market map but was the 1984 Audio review by B.Pisha because this magazine had higher circulation that STP.
In reality the cartridge had succes not in the " high-end " niche but out side it.
In those old times the MC 2000 was the more expensive cartridge down there: 2K because needs the T2000 and was a new road to Ortofon when its top of the line was a really good performer the MC30 that had a price of 600 plus the T30 SUT,
I was fortunated to bougth it at very special price directly to Ortofon because in those times was not an Ortofon distributor in my county México and from Ortofon I bougth the MC3000, MC3000MK2, MC5000, etc.
In reality Ortofon was out of the high-end market because its great cartridges were not reviewed by the high-end magazines. Your 7500 is a good example: no one cares about Ortofon was in the mid-fi market and was magazines as Audio who really help to some high-end audiophiles experienced with.
You are an example of what I'm saying here: you know about the MC2000 or the 7500 here at Agon several years after those cartridges appeared in the market. In the Asia market audiophiles had and have in very good place Ortofon through the SPU models and today new catalog.
Reviewers turn around their faces to Ortofon with the Jubilee and latter on the A90 and its today sucess came with the Anna.
