I think it is something of a crapshoot.
When you audition a cartridge, you are also auditioning the set-up, and set-up is at least as important IMO. By that I mean that I have heard modest cartridges sound very good, and expensive cartridges sound bad.
Unless your TT is very quiet, and your tonearm can be adjusted every way from Sunday, you will never get everything that a cartridge can deliver. And TT don't wear out, neither do tonearms.
So I suggest that you upgrade your TT and your tonearm. Worked for me, but YMMV.
