With any MM high output cartridge, its worth it to pay attention to proper loading. The inductance of the cartridge in parallel with the capacitance of the tonearm cable sets up an electrical resonance that is just ultrasonic of else in the extreme upper register of the audio band- acting like a 20dB treble boost. Once this is sorted out you tend to get less surface noise since its no longer being exacerbated. Obviously a lot of people that left the analog world never addressed this problem; IMO setting up an analog system properly is its biggest weakness. Its sort of like designing a speaker; if you don't know what you're doing its easy to put some drivers in a box that will make sound; quite another to get them to behave and sound like real music.
Maybe you shouldn't come out and lecture people when you don't even know that the AT-OC9/III is a MC cartridge...
