Fidelity Research cartridges


Any FR cartridge experts out there? Raul? Dertonarm? Syntax?
I have had an FR-7 which I bought a while ago. I tried it ever so briefly when I got it on an arm I now recognize as not being able to handle that weight (close, but no cigar). I just now pulled it out for kicks and after getting it adjusted with the big counterweight, I am VERY pleasantly surprised. Actually, I'm feeling kind of bubbly. It does not dig out the utmost in detail, but it just sounds very right.

Are there any other FR carts out there which are real steals if still in good condition? I know the MC-702 and the FR-1Mk2 and Mk3f by name, with good reps being assigned to the Mk3 and the MC-702. Given that the MC-702 and the FR-7 look quite similar, and they were offered at about the same time, what is different? And is the FR-7 just an integrated headshell version of the FR-1Mk3?

Thanks for sharing your observations! I assumed these were all technically identical to the Miyabi Standard. But I did notice that  Krell had two different model numbers, which suggests there might have been some slight sonic differences. I also noticed that the shape of the body of the various Levinson brands is slightly different than the body of the Krell models and the Miyabi Standard. But I guess these were all just variations on the same theme. And what a theme......

As for other versions, I remember there was also one with a carbon fiber body made for Mobile Fidelity. I'd be curious to hear the influence of the different body material. One reviewer also mentions Klipsch as one of the incarnations, but this is incorrect.

I've seen pictures of the 47Labs model, but that's a rather ugly plastic job compared to the others. The rare Ivory on the other hand looks gorgeous. Apparently this was the first Miyabi model. 

Probably the closest one can get to the sound of the Miyabi Standard from a new cartridge is the Fuuga, a concious attempt to resurrect Takeda's creation.

And here was me being complained at for comparing a Benz lps to and fr7-f to purchase 😉
Yes, it’s unforgivable to divert attention away from the FR-7, isn’t it? 😉

Getting back on the right - uh - track, changing the P2S distance of the FR-64S (or FX for that matter) when using the FR-7 is not a very good idea.

With P2S distance at 230mm you get perfect Stevenson alignment (the stylus ’hits’ all three ’o’ points on the Feickert protractor). This is clearly what Ikeda had intended. Changing to 231.5mm changes the geometry of the tonearm to Baerwald, but it will not be possible to align the FR-7 to this geometry. At least not according to the Feickert protractor. With the fixed headshell arrangement of the FR-7 there’s no way to adjust this.

I did try the Baerwald geometry with other (adjustable) cartridges, but I don’t hear the sonic benefits compared to Stevenson, so I decided to stick with Ikeda’s original specifications in all cases.
Dear chakster, I am not as patient as you are . So I can't wait till I
find whatever about this ''mysterious''  Takeda '' Ivory'' cart. Next
to your impressive cart collection you also have many carts pictures
so I hope  also Ivory?
