it does prove a benefit. I used the ruby with a new subplatter and after adding the nitride there was a drop in the noise floor. steady as she goes and for short bucks it is a fair improvement. Is it worth it? Yes.
Silicon Nitride vs Ruby bearing for Rega P5
I upgraded my P5 last year with a groovetracer subplatter and ruby bearing for an improvement my wife called "shocking". I've now come across the silicon nitride bearing and have one in hand. I'm reluctant to turn the TT upside down, swab out the well, etc. if the change of bearing isn't going to provide audible improvement. Anyone try this before? Will appreciate your thoughts.........
