Tonearm resonance

What's tonearm noise? Are the bearings loose? 

Not noise, resonance. Vibration through the tonarm from the stylus raising the noise floor.

I would buy a TT with the option of mounting your own arm, preferably the option to add a second arm.

A good used one gives you buying options and saves money or gets you more for your budget.

Original arm could be S arm with changeable head-shell for alternate head-shell/cartridges (one might be MM/MC/Mono), or an arm that has optional arm wands, like VPI Unipivot ..... Technics bpa-500 base alternate arms.

Any members know of other arms with changeable arm wands _______?

I don’t see a compliance mismatch so unless something is wrong with the arm bearings or with the cartridge, there shouldn’t be an issue. How do you know there’s resonance? If you hold the arm pillar with one hand, and the headshell with the other, do you detect play or is there no movement?

If you are experiencing "resonance", consider a better turntable before upgrading cartridge.

You could try wrapping the arm with 10 turns of PTFE tape halfway up and at the bearing end as an experiment. You could also try increasing the mass of the arm by adding another nut to the bolts or using brass instead of aluminum etc.
