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?

Dear friends, since i bought the uber rare FR-7fz i have to rise some funds for this expensive hobby. If anyone interested in my FR-7f in exellent condition let me know. I will keep only one cart for myself, another one looking for new home.

The sunlight was nice today to make a picture of it:

Dear ddriveman, I have read and reread your ''mini-shootout''
many times. The reason is ''obvious''. It is very satisfying to
see confirmation of our own opinion or judgment. In addition the
price comparison between the winners made me feel as a very
smart person (grin). I noticed the mentioning of Ikeda 9 C, mk III
which was, alas, not possible to adjust optimal during the test.
But the ''injustice'' done to the ''poor thing'' is corrected by your 
addendum. However you deed not vote for the FR-7fz as equal
to your (beloved?) Coral stone so your praise of the 9C,mk III
above the FR-7 FZ is not very convincing. I myself have no problem
at all to love Maria equal to Silvia despite their different qualities.
In this sense I love my FZ equal to my C9,mk II. However i just
got the REX. The latest of Ikeda's cantileverless kinds. So I
fall in love as never before and forget Maria as well Silvia.
I seem to agree with ''American Marx'': ''If you don't like my
principle I have other''...
@ddriveman is your EPC the integrated headshell version. I have the silver MK3 and it is absolutely fantastic sounding.

It is so smooth yet reveals everything without any listening fatigue. I guess that is down to the super flat frequency response. 

It also has a great bass response.

I also have no suspension problems.
Ateal,

Yes, my technics EPC100MkIV is the thegrated headshell version in P Mount version.
This is great to see all this information here from experienced users.

I just got a FR64s and FR 7f that I hope to assemble this week and try. I also have the Koetsu RSP that I will attempt to put on the arm with a Jelco headshell for now. I do have the lighter counterweight to use as an option as well.
