If you have the arm for it... That's an interesting question. I don't know the answer.
I have an Eminent Technology II, (mounted on on a VPI HW-19 MK II) I'll have to dig out the ET owner's manual to see what the specs are. Since the tone arm (a boron tube I believe, or some material that makes it stiff yet light) rides on a column of air, I think a heavier than usual cartridge might be too heavy.
And to all others, thank you for the responses.
I'll check out LP Gear.
I also sent an email to Soundsmith asking if they can rebuild the Carnegie. If they can, that might the more cost-efficient way to go. I also asked them a few questions about their cartridges. No response yet.
