FR66s vs Ikeda IT-407 CR tonearms

Dear @nkj : Do it a favor and before you pull the trigger with Stevenson A try to understand how that kind of alignment degerades the cartridge signal against Lófgren A or B.

It does not matters which P2S you choosed the Stevenson A alignment has higher tracking distortions all over the recording grooves but the last 3-4mm inner grooves of a total around 90-92 mm.

So you have not advantages with that alignment but only severe degradation to the cartridge signal because those higher tracking distortions and you can't do nothing about.

The best way to go is to choose Löfgren A/B alignments using  Dr. Feickert protractor. For me is the best way to go but it's up to you. 

Regards and enjoy the MUSIC NOT DISTORTIONS,

Thank you @rauliruegas I will experiment with those geometries.

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?

@maxgh
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.
