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.

Dear @nkj  and friends: Please read this post about. That's why makes no sense to any one folows using Stevenson A alignment:

@nkj  you can use either Löfgren A/Baerwald or Löfgren B with out modify the FR 230mm P2S spec and will have lower traking distortions that with Stevenson A no matters what.

Anyone aware of the IT-345 effective mass?

IT345 CR-1 handles in my system pretty much exactly as the IT407 - I don't think it's any less effective mass than the 20g of the original 407 despite the longer length - that may be the chrome finish or some other aspect.

Ikeda it 407 has an effective mass of 35-40g, the 345 a little less maybe 30-35g. That comes from the source.
