FR64s & Orsonic Av-1s Effective mass ?


Hi Good folks!

I have an FR 64s with original headshell. Have ordered an Orsonic Av-1s/ 10 grams, to meet better compliance/ resonnance matching with higher compliance cartridges.

Any idea what the effective mass will be with this combination?

Would be funny to try for example how my London Decca Super Gold would work with this arm..😀

cleeds, While Raul’s English may be a bit fractured at times, he is never "confused" about any of his underlying beliefs, as I am sure he will soon tell you, where the FR64S is concerned. But I agree with you; I set mine up expecting the kinds of problems Raul has repeatedly described, but I don’t hear them so far. In fact, I am breaking other rules as well, using a high mass arm with a high compliance cartridge (Acutex LPM320). I am still giving Raul the benefit of the doubt, because I do respect his opinion, except when he accuses me of "liking" distortions. Before I draw final conclusions I need to replace the 64S with some other tonearm that is both lower in effective mass and higher in "dampening" characteristics, keeping the turntable (Victor TT101 in re-enforced plinth) and cartridge constant.

Dear Lew, You are right about Raul. He is never ''confused'' about

those whom he does not like. Say Dertonarm. Well if Dertonarm

was ,uh, more critical about those damn FR/64/66 Raul may have

liked them. The strange thing however is that cleeds sold his FR-64

but Raul deed not. The humans are , I think, inscrutable.

Nicola, You raise an interesting question:  I wonder how many of us now own or ever did own an FR64S or FR66S.  And among this group, what is the opinion of the tonearm in terms of sonic qualities? 

I will start by saying I own one and my opinion so far is positive.
(I think the voting among FR64S or FR66S users can be simplified to "positive" or "negative".)

Maybe this should be a separate thread, but it does relate to the OP's conundrum.  Nevertheless, if he would rather squelch this investigation, so be it.
Raul is actually the only person I've ever heard who didn't think the FR-64S was an outstanding pickup arm. I've heard the FR-64S on a variety of turntables and in a variety of systems and it has always sounded excellent. Perhaps he bought a used one that is defective. That might explain it.

Dear Lew, I admire the ''mechanical beauty'' of the FR-64s of

which I own the silver and the copper version. I also own the Ikeda

345 which is, according to J. Carr, Ikeda's best. But I have no preference  for one above the other.

Cleeds, Whatever one may think about Raul I don't believe that he

would buy an defective FR-64/66 . If he still owns both they should

be in excelent condition. If I could afford the FR-66 I would make

him an offer (grin).Â
