I believe oustanding Argent MC cartridges are all US made in the 80s, but they are very rare and hard to find nowadays. Argent made diamond, ruby and sapphire cantilever versions. The company also made acoustic room lens before they disappeared from the market. Low compliance, high output model Argent MC500HS with sapphire cantilever sounds amazing, i wish i could put my hands on some other argent cartridges. And would be nice if anyone else here could share experience with Argent MC cartridges (reviews, catalogs, personal experience).
