Sorry for digging up this old thread, but my current table is a Technics SL-QD33 with its stock tonearm (most low-end Japanese tables have non-user-replaceable tonearms, to the point that if you upgrade your tonearm, then the automatic start/return features may not work correctly). I currently have an Audio-Technica AT92E cartridge whose stylus had not been changed at all in eight years. Unfortunately, a new stylus costs almost as much as an ENTIRE new cartridge! [By the way, my cartridge has a bonded .3x.7 mil elliptical diamond stylus - but I should have known better: Bonded means that the diamond had been glued onto the metal cantilever (as opposed to nude-mounted, in which mounting method involves cutting an extremely narrow groove around the diamond tip, and trying to somehow jam it into a smaller hole in the metal cantilever). And bonded styluses (or is the plural of stylus "stylii"?) don't last very long: The glue or adhesive is apt to weaken and wear out, causing the diamond to eventually fall out.]
So, I know the general rule of thumb is the appropriate cartridge for my Technics turntable shouldn't cost more than the original MSRP of that table (in this case, $199.99 - but I had paid $149.99 back in 1989). Given that, should I upgrade to a Grado Prestige Silver or Gold cartridge? Or, in the $80 range, a Grado Prestige Blue or Red, or an Audio-Technica AT331LP? Or, should I just go with another sub-$40 cartridge (such as another AT92E), or go with a Grado Prestige Black or Green? Or, should I just buy the cheapest cartridge available where I shop at [which means an A-T AT90E, with an 0.7 mil conical (spherical) stylus]? (NOTE: I'll need a P-mount cartridge for my particular table.)
And for music listening, which type of stylus is better? Conical (spherical), or elliptical?
