Dear @ml89009 : best tonearms? not an easy question with out its cartridges couple.
In the other side could be good first than all to define the characteristics that and " ideal " tonearm must has to at least have a reference against we are comparing to.
I for example we ask to thiose audiophiles that already posted : why the Basis Vector or the Victor 7045 are the best could be interesting their responses about.
Only an opinion, have fun.
Regards and enjoy the MUSIC NOT DISTORTIONS,
