Balls.....

Who here has upgraded their turntable platter bearing with a ceramic ball? What were your impressions of the upgrade? Worth it, not worth it?  I have a VPI non-inverted unit. It appears there is a gentleman in New Jersey that performs the upgrade.

I did a number of transactions with Steve some years ago when I was running VPI, reputable business.

Slaw, thank you for the link. Shall have to research the oil as well. Right now full synthetic 10-30 Mobil is what’s being used in this one.

I tried Mobile, can't remember the weight and/or if it was synthetic now. The Motul, is designed for racing engines. I bought mine at a local cycle shop.

I've tried three different bearing materials in my TT. Started with stainless steel then went to "Alumina Ceramic" & finally to "Silicon-Nitride Ceramic". Although the sound quality increased going from SS to "Alumina Ceramic", it increased much more (similar to Slaw's description) going to "Silicon-Nitride Ceramic". I've added a link to the bearing I'm currently using below.
