It’s not pointless but like have been said you will not get the best out of it. If it’s way overkill, that money will yield better performance elsewhere in the system.
I damaged my Roksan Shiraz a while back, since I did not want to have a Shiraz again I was contacted by someone who wanted it as he can get it re-tipped. I asked what turntable he was going to put it on, I got a reply that it was a Pioneer automatic turntable. I tried to persuade the guy it would be a waste of money to put a £3000 cartridge on a £600 turntable. Anyway he wanted it so I let him have it, he got it re-tipped.
He installed it on his Pioneer turntable, on first listen he said he was happy but it’s only marginally better than his previous £150 cartridge. I replied if a £3000 cartridge is only just better than a £150 cartridge, then something is wrong. I did not want to tell him I told you so, your turntable is not up to the job.
Anyway it turned out he had not set it up properly, a friend can round and set it properly for him and now it sounds a lot better. I have not heard it, but I would say he is still not getting the best out of the cartridge but hey he is happy.
