With your favorite type of music, and preferring Mono, what you want is a conical stylus. If you can still find one, the Pickering NP/AC cartridge is a high output punchy cartridge with a good frequency range and it comes with a conical stylus. These are the same as the Stanton 400 series. If you are meaning Stax and Motown 45's, then definitely you need a cartridge with a conical stylus and preferably jumpered to Mono. For Motown 45's, you need to track them at 3-5 grams. The original Motown 45's of the 1960's into the early-70's were mixed really hot and were difficult to track. You almost didn't need an amplifier to hear them. In the 1970's, Motown backed off on their mixes and began using a .7 mil groove on everything as well as making stereo 45's. The first of the Motown Yesteryear re-issue series used the original mono masters but gradually also switched to the .7 mil grooves and upgraded many to the stereo versions. On another subject, probably the first time we were able to hear clear and clean versions of the original Motown Mono recordings was the first Hitsville U.S.A. CD boxed set. You definitely don't want to play those Stax and Motown 45's with a Shure M97xe cartridge. That is like putting high performance expensive racing tires on a Yugo. Way overkill. And then blowing big bucks on a Jico SAS for the Shure to play Stax and Motown 45's? That is pure insanity! The cartridge manufacturers designed a cartridge to sound a certain way and provided their choice of stylus to achieve that sound. Making any modifications or putting in a different stylus will give you a different sound and it could be better or worse. As a rule of thumb, I try to use only original replacement stylii when I need to change them.
