Any experience with Phase Tech P1 or P3?


I am considering a cartridge upgrade and was interested in learning more about these cartridges. I appreciate any help.
Deck is Thorens TD321 with Sumiko MMT currently using Grado Sonata to good effect. Plan to transfer Sonata and was considering upgrading the cartridge. I like the soundstage and mid range vocals of the Sonata.
