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?

No wonder Ikeda returned to the ''old kind'' in his latest 9 series.
Actually Ikeda never returned. As far as I am aware, Ikeda had nothing to do with the current range of Ikeda cartridges.

Thanks dover, Do you mean that the ''new owners'' produced this new ''9 series carts''? So I can still admire our ''old Ikeda'' (grin).
BTW what is your opinion about those ''cantileverless kinds''?
I am wondering why  those Decca  admirer never discovered 
this MC kind of dynamic wonder?

As you know I have an Ikeda Kiwame, having previously had the original Ikeda 9. I like them very much, they are quick and very open through the mids - easily the best cartridge for me back in the 80's.

The Decca London Gold with Garrott Microscanner - very quick but the Ikeda at its best has more flesh and bones through the mids.
I first had the Ikeda back in the 80's - at this time it was very rare outside of Japan and certainly no magazine had reviewed it. This is why it is relatively unknown. Rowland Complement was the only version known in the US.

The main issue was variability, some tracked beautifully, others were difficult.

Subsequently, my Dynavector Nova 13D which I have owned since the early 90's, has more resolution than the Ikeda particularly in the mids to upper mids and tracks beautifully since it was last upgraded by Dynavector Japan with Microridge stylus and other tuning.

I dont have much experience with the new Ikedas, I have heard the Kai, preferred it to the Air Tight cartridge on the same TT. In some ways I think the Ikeda 9TS is more musical than the more expensive models - but thats only an impression from very brief listening in desparate systems.
Ikeda-San passed away last year, find all his legendary cartridges here.
There are 14 different versions of the cantileverless Ikeda 9 handmade by Isamu Ikeda himself.
Thanks chakster, I had no idea that there are so many. Anyway I am glad to see that Ikeda admirer are growing (grin). As you can see
even choosy Dover is one of those. While I decided not to buy any
new cart anymore this ''damn Dover'' caused me to search for the Dynavector Nova 13 d. I found one in UK in NOS state and hope 
that is still  available.
