@gochurchgo I’m not a cartridge guru, but I am using the Phasemation PP-500 on a Technics 1210G (stock arm) with a Phasemation CS-1200 headshell (13.7g) and Oyaide BR12 mat (5mm). I’m definitely enjoying what I’m hearing...
Also, I believe the low compliance you are quoting above was measured at 100Hz; Anamighty Sound measures the PP-500 at 14x10-6 at 10Hz, so medium compliance. The Phasemation/Technics stock arm combo is fairly common in Japan.
