I have NOT heard his cartridges, just ones with new cantilevers and tips.
I'm lucky, live only 35 minutes from him, I’ll listen to one he rebuilt completely on his system when I visit him soon.
I have heard two he re-tipped for my friend here in my system, and 2 he re-tipped for me in his system and my system
He has one done for me I need to pick up.
I trust what he says about his cartridges completely.
