It does not have one possible sound. You can have a cartridge too stiff for a very low mass tonearm. It will cause some resonance in the interaction between the stylus and the arm mass. And, you can have a cartridge too compliant for a tone arm with more mass than required, That will also distort the sound because the stylus will not be stable as it tracks the groove. All tonearms affect and will color the sound of every cartridge. As long as it sounds good/great to your ears? That’s what counts. I used to be a repairman for a vintage TT company, and sold audio after wards. No tonearm cartridge combination will be 100% neutral in the truest sense. What matters is what sounds good to your ears. If you want to know what is as close to neutral as it gets? Get your hands on some master tapes, and play on a state of the art reel to reel. Otherwise... shoot for what will sound good to your ears. There is no perfect match between a tonearm and cartridge, as far as neutrality. Only a match that sounds perfect to you, is a good match. High compliance needs a low mass arm. Low compliance may need a higher mass arm to prevent the stylus vibration effecting the arm vibration... But, there are even exceptions to that, as with a Decca London. Again.. if it sounds good? Be content.
