FR64s & Orsonic Av-1s Effective mass ?

Good to read Raul’s broken record about his distortion "knowledge"
i bet, even when he is 6 feet under, we will hear it from him... And his last word will be: "Distortions"
Never able to move the sonic curtain in the last 6 years.. But always present to spread the outdated opinion which is covered as " knowledge".I think, distortions can be in brain, too
Btw. Your german friend, DerTonearm became a very well respected designer and his Arms, which share FR qualities, won many awards and side by side comparisons.
How long we wait now for "your" benchmark Tonearm design made in Mexico? Five years? 

rauliruegas " ... Problem is that you can’t , not even in dreams, imagine ..."

Raul, you are amazing! Not only do you know what people think, we now learn that you know what they dream. That is truly remarkable and we are so unfortunate to have you in this forum. That you for conversing with us, and sharing your wisdom with us. We are all in such debt to you!

Raul, As I mentioned once before, the cartridge I am running on my FR64S is an Acutex LPM320STRIII.  Acutex say the compliance is 42; I forget whether that is a static or dynamic measurement and at what frequency. I also own the snub nose earlier version M320, but have not tried it yet. Yes, it is a great cartridge. I wonder whether paradoxically MM or MI cartridges like the Acutex might actually work BETTER than MC types on an undamped tonearm such as the FR64S, because the MCs are said to put more energy back up into the arm wand, perhaps due to low compliance.  A high compliance cartridge is acting like a good auto suspension to minimize energy that might go back up into the cartridge body, and therefore there is less need for damping the tonearm proper. Plus, I said my piece on mass loading. Just a thought.

@syntax : Your skills/abilities to avoid answers to my specific questions are " admirable ".

I never ever read or " listen " that you and your audio advisor ( btw, any one. ), that " die for FR marvelous performance/design ", any single argument and reasons WHY that FR helps in better way to cope/cover with the cartridge needs against a damped Tonearm and headshell designs and WHY the damped tonearms are an inferior kind of designs WHY does not helps to be a better cartridge match as the non damped tonearm designs.

So, you have other opportunity to put real light with specific arguments/facts of all the cartridge benefits of undamped designs against damped tonearms and headshells other that " I like it or sounds terrific ".

Btw, JC already gave you and your advisor a precise answer for all of us can learn and in diferent threads not only my posts but other people posts gave you very specific arguments about that no one prove are all wrong.

JC is not only the Lyra designer but he made and make cartridge designs for other " people ".
He was and is so succesfuly because not only his high knowledge level on design but because made and make his cartridge voicing and even makes voicing/tests top competiors cartridges and for do all that he has the right skills ( other than be a music lover. ) to do it.
He already tested almost any tonearm you can imagine ( included the FR as he answered to both of you. ) with " dream " TTs and electronics.

In the other side no one knows better the Lyra cartridge quality performance levels than JC and this is an additional fact that till today both of you never posted any single specific argument against JC " certified " arguments.

My " broken record " on DISTORTIONS came not ( as you said. ) from 6 years ago but years before that when I learned not only about tonearm or cartridges but about DISTORTIONS in any single link in the audio system chain and how to be aware of those distortions and what to do to put each one at minimum or near as we can.

In favor of Agoners and audio industry please don’t try to avoid again your good founded facts and give us that light/answers.

Regards and enjoy the music,
R.
