I'm not thrilled by a description that starts with
"This cartridge digs into the grooves and gives a musical presentation with very good detail, excellent bass and natural midrange. I have had super pricey cartridges and I don't miss them."
I dunno, for maybe $15 more you could have a respected, genuine Audio Technica AT95e with a genuine AT stylus and quality. Maybe less, if someone is promoting them. This is a great sounding cartridge for the money and keep in mind the stylus is the critical part of something like this. The 3600E reminds me of the lowest-end Audio Technica AT3600, the difference being in the stylus build.
I would bet the CF3600LE (proprietary for LP Gear) includes the bottom of the line, least expensive elliptical stylus that AT produces. Description indicates carbon fibre (nothing special) cantilever with elliptical stylus. Both products will work, but between those two I'd rather have the AT95e on my tonearm.
Steuerpimpel, Control nipple stud, Guide (and sometimes it's not even listed or numbered) -- Whatever name for them is found in the factory Service Manual; old worn and cracked ones can rub tonearms just half-way. Or, not at all. Keep 'em guiding and gliding.
