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'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.

Thank you for the contribution boxer12. On what brand of turntable was this upgrade performed?

"That gentleman in N.J. has the same address as VPI! It must be VPI that does the bearing upgrade! "
Yea, it's Steve at VAS Audio. He is in the same building as VPI, right next door.
About an hour from me, handy to have so close as he is a top notch cartridge man.
