Wadia 830 basic vs Theta Miles balanced

I am going amp direct. Two competitors from the same era.Any owners of both?
I have heard both and the Wadia sounds way better than Theta Miles.
Besides, the Theta uses a discontinued Pioneer stable platter transport, parts are hard to find.
Both Wadia 830 and Theta Miles use discontinued transport mechanisms from Pioneer. They are still available though.
Thanks for the info. Parts supplier ?
