Adding mass to a tonearm


I would like someone to explain to me why adding headshell weights doesn't really alter the mass of the tonearm that much when figuring cart vs tonearm compliance. I have a Denon DL-103r and I keep reading that's it's for high mass tonearms. I also hear that adding headshell weights doesn't really alter the mass. What gives?

I want to try a DIY on my Pioneer PL-530 turntable tonearm where I mask off the arm such that only the chrome arm on the headshell side is visible and spray it with Plastidip. This would seem to add mass and resonance control. If it doesn't work the I can just peel it off.

I bought various screws for my Reed 3p tonearm to add weight, because most vintage MM cartridges i have are too light, still usable, but the counterweight of the toneam is too close to the pivot, so those 12mm cartridge mounting thumb screws are 1.51g each (about 3g for pair) and made of the gold plated brass (non magnetic). Available here in various size and weight. Recommended!
