To tooblue,
You are lucky enough to get 2000 hours on your zyx. My airy 3 suspension at less than 1000 hours was destroyed and on my French forum 6 members got reliability problem with zyx, so for my next cartridge I have bought from another company.
I was very pleased with the sound but buying something not very reliable and then giving a big amount of money to get a new one, not for me. I have better buy a model which can easily been retipped for cheap as I listen a lot.
