FR66s vs Ikeda IT-407 CR tonearms


Has anyone compared the FR66s to the newer Ikeda IT-407 CR1 tonearm? Any thoughts? In previous years, the Ikeda was available with either copper or silver internal wiring but the recent models don't mention anything about the tonearm wiring. Can anyone comment what type of wiring is used in the latest editions? It would seem intuitive that the later Ikeda IT407 should be a better performer than the FR66s having improved material and bearings over the FR66s but the proof is in the hearing.

Do you still say that only the Dennesen Soundtracktor can be used to set-up the FR64s and FR66?

I just bought a very expensive SmarTractor to use on both of my FR64s's....

I do have a very old, plastic Dennesen Soundtracktor... but would much rather use the SmartTractor if I can, as it would be much more accurate.
Dennesen looks like Dr.Feickert, but with much less options!
have you seen a Feickert protractor @rich121  ?
Dertonearm’s protractors are based on the Dennesen, with many important improvements that permit much more accurate alignment.

I have the Dr. Feickert protractor... the model from 2005, just before he re-issued it.
I upgraded to the SmartTractor which is much more accurate.
Just use the smart tractor. It invorporates the Dennesen and is more accurate. syntax uses it too since it was released by dertonarm.
