What is a Headshell and what does it do ?

Phono cartridges sound different! I have a moving magnet (mm) mounted on one headshell and a Moving coil (MC) mounted on another. Each, provides something different to the musical presentation. Being able to switch cartridges quick and easy is a plus. How you could have a TT with multiple tone arms but that gets pricy.

Wow this question is to tough.

It adds some weight to the Arm for better tracking

Ok , if you trade out headshells with cartridges mounted in them , is there a new set up procedure required ? Or do you just remove one , install another and play records ?

Thank you

Except in the unlikely event that the two cartridges need the same VTF, antiskate and arm height settings, those will have to be adusted with each cartridge change.

Additionally, much depends on how accurately the headshell/tonearm connection was machined. If it puts the cartridge in *exactly* the same position each time its removed and replaced, great. Of course no mechnical interface is perfect. To whatever degree there's room for variation, you would need to re-check overhang, zenith angle and azimuth.
