Then buy "what you can actually buy".
I bought all the cartridges online, not only those I have mentioned (they are easy to find), but even much more rare ones for my collection of the best cartridges.
You don’t know that JICO made styli for discontinued cartridges too (
even S.A.S. for some vintage MM models) ?
You don’t know all those new carts like Grado, SoundSmith, Audio-Technica, Nagaoka, Garrott, Goldring, Ortofon that you can buy almost everywhere (including models for $500) ?
This thread is a good demonstration of the different preferences, some people prefer cheaper MC to more expensive MC, some people prefer MM or MI to many cheap MC, some people just search for the ultimate cartridges in mint condition (or NOS) from the past in every category (MC, MM, MI).
But some people are too lazy to search and discover things, they want others to tell them what to do and what to buy, but it’s not necessary a good advice, often their mentors have nothing to compare those new carts to. Experience is a good thing (not the price) !
