Haha.
No experience with FR. I was told that the Ikeda is the best new production arm for Koetsu. I don't doubt the FR 66 might sound better but haven't heard it. I had a Blue Lace on my Ikeda and can confidently say it was a good match. Also used it with an Arche headshell and Furutech silver leads.
I've owned a Blue Lace previously but stupidly sold it to help fund my Artisan Fidelity project. I would have just sold my other tables had I known that the 301 was going to end up being my favorite. I have heard that the blue lace is very similar with it being a bit more neutral than the Coral. I need a bit of extra texture and weight since my system is a tad lean.
I currently have an Ear 868PL (I love Ear) with a quad set of Amperex 7308s. I will move to the 912 next year.
Very interesting! I have heard consistently the same suggestion about the difference between the Blue Lace and the Coralstone -- theoretically because the Blue Lace stone is a bit harder (on the hardness scale) than the Coralstone stone.
You would have to hear the Ikeda versus the FR for youself. (I have to take this advice for myself, too.)
I know shakti and bonzo75 agree that the undamped stainless steel armwand on the FR-66S gives the Koetsu energy and life, but one audiophile's "energy" and "life" can be another audiophile's "over-detailed" and "analytical" so, as MikeL and bonzo75 and Peter A write, we have to make these comparisons for ourselves.
