fiogf49gjkf0d At a risk of being severely bashed...I came across this old cart. There seem to be a Bavarian mafia
promoting it on audio-gone.."transparent, neutral, indestructible...blah blah blah"
I'm wondering if despite being a fetish of the mentioned club,
there might be some merit behind this cart?
Anybody with a good 1st hand experience?
There seem to be different versions: FR7, 7f, 7fz.
How do they differ in their reproduction abilities (if they have any to talk about)?
Cheers,
N-set

fiogf49gjkf0d I think I remember the first FR from the mid-late 60s, and the FR7 came maybe 10 years later, so it could be pretty damned old. Wasn't this stuff from "Ikeda Sama"? Anyway, many older cartridges had/have damping materials that were not ozone-proof, and/or wires or connections that corrode over time, so caveat emptor.
As for German endorsement, whazza matter with a nice, new EMT?
Best regards,

fiogf49gjkf0d which is troublesome...They claim the suspension is sealed so the rubber do not corrode.
There is also someone who pressure fits new styluses.

fiogf49gjkf0d Shake yourself, N-set!
Surely, there must be more practical options?
Aren't there plenty of fresh, new throwback and cult cartridges available from legitimate, contemporary Japanese, Danish and German companies?
Sealed suspension, new stylus, my ass...
Best regards,

fiogf49gjkf0d This is the point, Paul: is it a self-propelled, self-ass-licking FR7 club or does this cart has any merit?
Old vs. new, new vs. old...
in the world of planned obsolescnce I do not know how to navigate.
There is a myriad of models, but what they are worth?
What's Ortofon worth with TOTL model every year or so? And Shelter?
If I see something like this:

what should I think of the modern cart industry? A cart with balls...or rather one ball hahaha!

fiogf49gjkf0d The carts from Fidelity Research were made until 1989. From what I know, the FR-7 series are different among with Impedance, Output and what kind of diamond cut they have. They last forever based on their internal construction and can be retipped quite easily. Extremely high tracking ability. One or two of them are a bit special, they were made for Japanese Press Plants to listen with them their Test Pressings, there was also a FR-1 / FR-702 available....
Mitch A. Cotter used a FR-7f as his reference cartridge (but with silver body, silver Pins....). At that time it was also possible to order these carts with separate Diamonds, it was expensive anyway.
The FR-7 is available via ebay, normally no big deal to get one, same with FR-7f, but that one became rare in the last year, fz nearly impossible, the Japanese don't offer it outside Japan anymore...
Most have very low output (0.16mV-0.20mV), fz is highest with 0.25mV, you need a high gain amplification, in combination with one of their FR-Arms (64 for example) they easily compete with everything modern today.
In Germany are a few analog groups, some build their turntable with a piece of wood and a knife and think it is great, some prefer old Linn, Garrads, Thorens as the only, real solution to listen to and others refuse to listen to Linn, Garrads, EMT's for various reasons (BS, Waste of Time, wrong generally, colored) and when they have to, they want money for that...another group uses Seiki, Verdier from France, Cotter and that's it for them ....Another group in this little country have the motto for their reproduction stuff "You will eat your heart out", they are arrogant, don't read Mags or communicate in Forums because they are all afraid of getting eye cancer from reading that nonsense, hate reissues and their owners and accept only 2 colors: black or white ... :-)
And there is another interesting Country: France
From there the real outstanding Japanese stuff was translated in the early 80's, introduced, built and there are also some very interesting audio circles ....

Very interesting post and I would like to point out that there is truly no common denominator between those groups in generally. I mean there is absolutely no common sonic considerations why one TT is better than another. I have seen some people who own a few top flying TT and have them to setup in the same room with the same rest of the equipment. Even running the identical tonearm, cartridges and cables I did not feel that the “comparing” was adequate. Over the years I have developed my own judgment pattern about the validity of this or that audio groups but it has hardly to do with the actual comparing the sonic output from the different TTs.

fiogf49gjkf0d Quote:
"Degradation of natural rubber can be caused by a variety of
environmental factors, such as elevated temperature, humidity, impurities,
mechanical load, irradiation and chemicals. In the presence of atmospheric
oxygen, the useful lifetime of many polymer products is limited by oxidative
reactions.
Radical attack of the polymer chain causes chain scission, crosslink
formation and crosslink breakage. Changes in the properties of polymers with
ageing depend on the extent of such reactions."
It not only oxygen that kills a suspension. It's movement itself and the heat caused by it too. And there is another killer: time.

fiogf49gjkf0d Sure, there might be older cartridge designs that sounded good in their day if someone knew how to use them, but even new cartridges exhibit serious unit-to-unit variations. Add aging and/or deteriorating suspensions, contacts, fasteners, wires, cantilevers, etc., and the numerical odds of getting a lemon go up exponentially. I am also skeptical of refreshing a cartridge by taking an old stylus out of a cantilever and pressing a new stylus into and re-using "the same" cantilever. The range of potential problems in a process like this is astronomical. Whose garage is it done in?
As for "broadcast standard" or "studio playback standard" cartridges, I have owned several over the years, and these designations do not ensure unit consisistency, immunity from deterioration, nor Music in the home.
Not to impune the FR-7f, etc., but just some due diligence, based on personal experience.
I suppose you've already looked to see if Ikeda has any current offerings?
OTOH, if you insist to buy the antique afterall, N-set, you will at least have another chapter for your Bildungsroman.

fiogf49gjkf0d I think the same Stitch has been bitching on the broadcast TSD's. Why test pressing analysis carts should be better than broadcasting?
Anyway, I do not insist Paul, I've just asked. Indeed, looking into the modern Ikeda there seem to be something...at least in a reasonable
price range: 9EM, 9R, blahblahblah

fiogf49gjkf0d Continuing my crawling in the sea of cartridge excrements, there is this Lumiere DST, inspired by Neumann DST-62 and highly praised by Stefano.
Difficult to get any reasonable info (at least some basic raw data), apart from apparent sample-to-sample huge variation, as the carts are handmade in some garage. I'm not even sure if the carts are still manufactured. Anyone with some experience? How to contact Lumiere? Thanks

fiogf49gjkf0d it's going to be a hit and miss affair. You can as well make a list, close your eyes and put the finger randomly , really .If you're short with cash (and I have feeling that you are ) just buy something lesser, not having cult status and what goes with that highly inflated price. Benzes are decent , Dynavectors too and there is little reason to get something which is prized in inner circles of black art practitioners/gurus. Best , W

Yes, I know. He is Syntax on audio-gone and by chance, when FR-7 surfaced in one of a threads, he's trying to sell one fz for a
stratosheric price. Miracously, in the same time another individual, Daniel-Dertonarm, was offering another fz on uk ebay hiding
for some reason under a different nick of lpsandvideo or sth. like that. His price was roughly 1/2 of Syntax's, maybe his fz was swimming
in a good Weizenbier for refreshing sound?

fiogf49gjkf0d Well, some say, he loves reading those postings, others think he raped his grandma or (and) will be responsible for the next earthquake in California, some bet he was a member of the well known German Anonymous Audiophile Alcoholics and left them because he converted to Coca Cola, some swear he is a member in the secret Analog Audio Assassination group who use digital Players for listening. Visitors saw at his Place Lyra Titan, Olympos, Transfigurations, Benz, Takeda Miyabi, Koetsus, several Arms, Turntables and were able to hear differences. Some audiophile groups hate him deeply because he is not interested doing someone a favor, he refuses to drink & listen...The world is a flat disc :-)

fiogf49gjkf0d why you feel you should show off with your equipment and it's price tags (on a-gone)
rather than results, but that's your choice. It's a thread about FR7 and the funny thing is
that in your show-off list above you do not mention it.
Since you know the cart, have you tried it on different arms than FR?
I have a free 3012R.
Cheers,
N-set

fiogf49gjkf0d Yes, they pop up here & there but that's not the point. The point is what's they are worth after 30+ yrs,
and if they'd hypothetically work in my situation of 3012R.
Some people compare them to modern ZYX carts UNIverse and Airy
(I've got one such a comparison by a private mail),
I'm not familiar with ZYX, but if ZYX is able to produce a caricatural one-ball joke quoted above then I do not
know if this comarison is a compliment or to the opposite.

fiogf49gjkf0d The 3012 is actually a fairly "flexible" arm, but to "develop" any arm/cartridge pairing might take a long time, and during this time you are pretty much on your own. The truth is, you may or may not EVER hear a cartridge the same way someone else heard it. And this may or may not matter in the end.
Surely, enough has been said about the "vintage" cartridges for any attentive person to make a decision about this particular matter?
Best regards,

fiogf49gjkf0d After dealing with a few individuals trying to sell me a FR-7, I've decided to kiss goodbye to this idea
and look into the direction which has actually been considered at this site: Decca Jubilee.
From several sources the the signals are that this might be what I'm after. Unlike the half-brain
US distributor quoted somewhere at the site, the UK London Decca manufacturing people are very cooperative and will
send me their demo Jubilee for an in-system trial. Nice!
The big challenge seems to incorporate it into 3012R and EMT930.... It puts a lot of energy due to almost non existent
cantilever damping and the knife bearing can rattle. The "Decca arm wisdom" seems to be damped heavy unipivots,
with precise bearings, but lets challenge it. Also EMT930 beats at approx. 3Hz -- the idler fundamental, which may additionaly excite
arm-cart lateral resonance.
Luckily I have the steel R version, which is internally
better damped as I learned than the alu one + nylon bearings. Putting an extra headshell weight
to the max of the arm (or machining an extra counterweight to reach circa 30g eff.) + possibly SME FD200
viscosious lateral (where the most needed) damping kit and lets see...
Cheers
