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.

It is with deep regret that I must convey the sad news that Osamu Ikeda passed away at the age of 92, on 2018-09-17, Japan time.
He contributed to analog audio in a manner that few can emulate, and will be sorely missed.
The Ikeda brand continues, in the hands of a younger generation of cartridge and tonearm craftsmen.

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.
