I replaced the steel ball for a silicon carbide ball. Steel thrust plate, steel axel with brass sleeves. On a Logic DM101. Wasn’t a huge difference. But subtle for the better. Changed lubricant at the same time, can’t remember the brand, from someone in the UK who modded Rega’s. So the lube contributed perhaps as well. The ball was sold as a good grade (of evenness, I guess). I am sort of convinced that the quality of its roundness/evenness contributes the most.
Kind regards.
