How do you know when to replace the stylist?

When he offers to style your Body hair!!!!

I would never let a stylist anywhere near my cartridge.

Sorry Stylus...Bummer can't edit original post. :o

Who can retip a MC cartridge and how do you know when.

Check with the dealer(s) of the cartridges that interest you. They can point you in the direction of re-tippers, and they can tell you how many hours to expect out of the stylus.

Benz Micro has a trade-in program. Soundsmith re-tips Denon carts, I believe.

Thanks Tvad...VERY Helpful
