Hi Travis. I read your last question about this, and didn't know the answer. However, since I do know that the SAEC is a knife-edge bearing design, I'd stay away from low compliance cartridges with this one due to possible bearing chatter. Since is it probably a fairly heavy arm, high compliance is also out. So to be on the safe side, a medium compliance cartridge will probably do the job with least chance of major problems. I couldn't find any effective mass specs for this arm on the web.
