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..😀

I'm sure that some day all of us will learn: or not?

Your question was answered before you asked it. Perhaps you might consider going back and reading this thread more carefully.

Here’s a little tip, Raul. When you write, "... WHY that FR helps in better ... and WHY the damped tonearms are an inferior kind of designs WHY do ..." the use of all caps is considered shouting. That gives contributors here just one more reason to ignore you.

In any event, no one here in this group owes you an explanation for anything.
Dear @lewm : A tonearm manufacturer " normally " makes his design for any kind of cartridge compliance included his kind of tonearm damping choice .

Feedback, vibrations, noises, resonances, distortions comes from everywhere ( TT platter, platter mat, LP, arm board, TT motor, air borne noise, etc, etc. ) in the room/audio system and the tonearm designer have to deal with all of them to achieve his tonearm targets.

Cartridge compliance is part of the cartridge suspension system that's " affected " by the suspension damping mechanism cartridge designer choosed and between other things the kind of dampers and damper build materials.

Each cartridge, independent of its compliance, has its own kind of vibrations/feedback/cartridge body ones, diferent compliance values only can change the amplitude or frequency where " vibrations/distortions can happen and of course tracking abilities.

In all type of cartridges a damped tonearm always helps against no damping at all.

Through our life, inside and out of audio world, we like several things that we know are wrong but we still are sticky to them.
Example: sugar/comercial chocolat are a human been " murderer " that always goes against our safety health but here we know is wrong and accept it ( does not matters that we go on eating sugar. ) and with the non damped tonearm we can't accept is wrong even with evidence against a damped designs.

What do we in the audio world?, nothing but try to be " self  convinced ) through that: " I LIKE IT " and that's all and that's why one gentleman posted here:

"  Raul is actually the only person I've ever heard who didn't think the FR-64S was an outstanding pickup arm. """


With that sentence he thinks is confirming he is rigth when in reality is wrong on that subject.

Anyway, as always a learning day.

Regards and enjoy the music,

Once again, Raul, you pretend to know what others are thinking when, in fact, you have enough trouble explaining yourself.

My remark that you quote means no more than it states: I've never conversed with anyone - other than you - that didn't get excellent results from the FR-64S pickup arm. And I allowed that, because you bought yours used, that might explain your confusion. When you buy used, it's difficult to know exactly what you're getting.

It's fine that you don't like the FR-64, Raul. I really don't care. But that others like it doesn't make them wrong. Your insistence that they are wrong is why I shall again return to ignoring you and the Pronouncements and Proclamations of Truth According to the Great Raul.


CLeeds, In all fairness to Raul, where do you go these days to buy a NEW FR64S?  In fact, so far as I know, Raul has owned his FR64S for a much longer period of time than I have owned mine; there's at least a chance that he DID buy his FR64S new.  I would wager that nearly all of us who have commented on this thread bought their FR tonearms as used items. I bought mine off eBay about 3-4 years ago, with "silver inside", from either 2juki or one of the other regular Japanese eBay sellers.  When I got it, the bearing was a little stiff.  Dertonearm advised me to just leave it in a warm place so as to allow the bearing lubricant to warm up, and indeed he was right; the problem just disappeared while the FR64S was sitting at room temperature in my house.  Other than a broken internal wire or a very stiff bearing that does not "thaw out", I don't know what else could go wrong with an FR64S that would not be immediately apparent.  Thus I conclude that Raul's opinion, whether we like it or not, is based on listening to a fully OK sample of the tonearm.
By the way, I am wondering whether the lubricant that evidently surrounds the bearing in fact does constitute a form of damping
