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..😀

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).

Interresting debate!

Got the Orsonic AV1S after some busy days with barbequing, beers and music. There must be no doubt that the AV1S was a much better match than the original FR64S headshell with the Super Gold. It sounds smother, cleaner and dynamics is really kicking. It is quite fun to drop the Decca needle now. And amazingly, the hum totally dissapeared😃!
According to HFN test record the ressonance are now about 9 hz. Still tweaking..
