Jared, If i were you i’d rather try Allnic Puritas, Miyajima Shilabi or Kansui on Thomas Schick "12 tonearm. I’ve owned the arm for 3 years and sold it towards my investments to Reed 3P "12 Cocobolo. The Shick is nice with low compliance cartridges, but Denon 103 and SPU are not the ultimate in this class (but best match for this tonearm, indeed). Also i think this is not the best arm for refined mid compliance modern MC cartridges with its stock wirings and $5 neutrik rca connectors. Schick is great with oldschool low compliance cartridges (don’t forget the EMT carts). I would go for used Miyajima instead of new SPU or cheaper new Denon. My low compliance (8cu @ 10Hz) vintage Argent MC500HS cartridge was great on Schick
, but even better on Reed 3p now.
