FR66s vs Ikeda IT-407 CR tonearms

The function of the knob with the finger screw is to adjust the lever so that it is level when the cartridge is at the beginning of the record. This allows the anti-skate force to be calibrated regardless of how the tonearm is rotated horizontally and to decline at the same rate as the cartridge moves across the record.

 The whole business about whose silver wire might sound better seems to me to be silly. Unless we think that either Ikeda or Kondo or Dertonearm own silver mines. All of these entities must buy their silver wire from some company that makes wire. It’s all very unglamorous. For all we know they all get their wire from the same original source. And Kondo’s claim about maturing the wire seems equally specious to me. All silver on earth is probably as old as the earth or very nearly so.

The purity of the silver and how it’s wound  or not wound, and how it’s insulated, all of those could possibly make a difference to sound quality.

My silver wire in My 66s was drilled from four 80 years old virgins and after that they dipped it into holy water....
The result is a increased sound space with a dynamic slam which makes me cry every time I listen to a record 
Better, way better than any remote control 😊

lewm,

My point about the silver wires is not who has better tonearm silver wire but that the existing FR64s and FR66s tonearms are about 40 years old and getting them rewired, either by Dertonarm or Ikeda brings improvements. In fact, I go to great lengths to explain that I hear no difference between Dertonarm's rewire and Ikeda's rewire. It's the other posters who have muddled up this simple message, claiming contradictions, fake news etc etc ...
Enough already! Jeez!

My post was just a general comment.  Not at all aimed at you or anyone else specifically.

I think there is plenty of room to discuss what topology sounds best and what insulation sounds best (of silver wire).  (Litz vs stranded vs insulated strands vs solid core/single strand and teflon vs cloth vs just an insulated coating.)
