I was looking at more expensive moving coil cartridges for my SL-1200G like the Ortofon Cadenza line or Clearaudio Concerto, but stumbled onto a few discussions on the Audio-Technica AT33PTG/II and AT33SA. These look like they could be relative bargain moving coil cartridges. The specs are somewhat similar on them, and I was wondering if anybody has compared the two. The look to have the right weight and compliance to work well with the Technics arm. The SA has a Shibata stylus vs. the more refined Micro Line on the cheaper PTG/II, but I've been warned that the smaller minor radius (only 2.5 uM) on the Mico Line may just pick up more noise, and that 5 uM is about as small as one needs to go (as on the Fritz Gyger, Ortofon Replicant 100, etc.) I think Shibata is 6 uM, which is probably close enough. I'd be interested to hear from anyone that's used either or both of these cartridges. Thanks.
