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..😀

An alternative way to get damping for the arm and/or Decca is to mount them on a Townshend Rock turntable, which has a damping trough at the headshell end of the arm. The Townshend damping system also reduces the Q of the arm/cartridge resonance.

One can't ''balance'' the FR-64 with an lightweight headshell and

cart. The old FR headshell is worthless while the Orsonic AV 101

is much better than the (lightweigt) Orsonic AV-1. There are

different FR-64 counter weights but difficult to get. The nearer the

conterwight to the pivot the lesser the arm mass. The lighter the

the headshell the less arm mass. LPgear sells and excelent

headshell for about $ 50. There are different names and prices

for the same (magnesium) headshell which is made by Jelco(?).

I bought 6 of those under the name ''Sumiko'' for about 40 GBP a piece.

why 101 it's better?

Dear Chakster, You probably enjoy making my life difficult with

your ''endless'' questions(grin). As you should know the stability

and rigidity of the headshells are very important. You only need to

look at both headshells to see the difference. Those small and weak ''legs'' on the Orsonic AV-1 are not very convincing. Besides, according to ''some Aussie'' they are produced in China. This means that they are also ''fake headshells'' . For their kind of prices I would also reproduce them if I knew how. The Orsonic AV 101 on the

other side is at present too complicated for the Chinese to produce

them . So they are probably made in Japan. I use them

for my best carts only . BTW I also own Dertonarm's Arche

headshell ( the best ever, sorry Raul) which I use only with even better carts than my best.

Dear @fast_mick : """ AT ART9 mounted on a similar turntable and the 64S/2M combo sounds equally as good... """

good for you that sounds " equally " good when both cartridges are way diferent, both are good cartridges ( already hear it both. ) but with diferent quality sound performance level. Even you listen it with two way diferent tonearms and with the 64 with its " terrible " dinamically vtf engaged.

Seems to me that other that you like very high distortions maybe your system has very low resolution and you are not aware of your system distortions. Perhaps some tube electronics not up to the task or even all SS one electronics with " poor " performance?

Anyway, subject is that any single cartridge needs a well damped tonearm/headshell.

Some/many audiophiles " die for " very high distortions and do not care about.
Of course they all are wrong but we live in a free audio world and we can choose whatever but this fact does not means in any way is right because there are many audio things that we like but are not right but wrong.

Well, we have to stay away from undamped tonearms and undamped headshells. Name of the game in audio is to achieve the lowest distortion levels anywhere and overall in any audio system.

Audio ignorance levels always is a problem for each one of us.

Regards and enjoy the music,
R.
