We're not talking about resonance in the tonearm itself (which can also be a problem, but quite a different one), but the resonance of the combination of the mass of the tonearm and the compliance of the cartridge. See for example <http://www.ortofon.com/support/cartridgetonearm-resonance-frequency> Ciao, -- FA A world of exhaustive, reliable metadata would be an utopia.
