The AT stylus on my old Sansui turntable was probably decades old, and no longer available. Even the one that AT made to replace it is no longer available. This one fit perfectly and works great.
I bought a vintage direct drive Pioneer PL-510S that came with a 50 year old cartridge. It sounded like an AM radio. After mounting the Nagoaka 110H, the bottom filled in and a warmth I was seeking was audibly apparent. It was more than worth the investment.
I bought this based on reviews I read here and elsewhere and I recommend this cartridge highly. You hear everything with this one. It sounds just as good as the Linn Addikt on another turntable. It really is exceptional and there is no need to spend more IMHO.
