Fidelity Research FR-64 vs. FR-54

I explain ( trhough an Agon post. ) in precise way that that picture that shows the cartridge mounted in its dedicated headshell was only to use it in my ad for sale Agon listing.

Raul, why would you mount, advertise and sell a cartridge mounted incorrectly in its dedicated headshell upside down. Do you sell your Essential preamp with the channels reversed inside the preamp for fun too ?  

I never mounted the 13D in my system with that headshell: never.

Therefore you posted a review of this cartridge without having listened to it in the Dynavector recommended proprietary headshell, hardly an authoritative review. Furthermore check slide 3, it is mounted incorrectly in your tonearm. Tell me, how do you review cartridges - do you just look a them. And of course you pass a review on a cartridge you have never heard - your Dynavector 13D had a non standard cantilever bearing no resemblance whatsoever to the original.
Raul, if you read my posts more carefully you may find the path to exceed your AHEE status and move up to my level. I am well past the cognitive development stage and am now at the AHAA level.

Cheers   

Btw, please read carefully this thread's information about the first Essential version:

https://forum.audiogon.com/discussions/experience-with-raul-s-essential-3150?highlight=essential%2B3....

of those gentlemans only A.Porter and F.Crowder listened the 3160 ( third version. No one but me the fourth that only I owns. ). I was at their places twice.

Dear Raul, are you trying to pull out names of well-respected members of this forum to support your views? If so, it is such an irony that you picked these 2 gentlemen to mention. Just look at what equipment they are using right now!

It is especially interesting that you mentioned Mr Porter, to whom I must give thanks to for his invaluable advice on Aesthetix equipment. By looking at the date of the post (2006), he probably was using the Signature version of the Aesthetix at the time, as the updated version, which he got later, came out in around 2009.

So, after auditioning your phonolinepreamp, he stayed with the “tube 30's alternative” (your words, not mine). He changed to the IO and Callisto Eclipse later, and then changed to the Allnic. It is interesting that the Allnic is using tubes of even older designs (if I am not mistaken) than the Aesthetix!

Also, I have reread the whole thread above, and it seems to me that no one participated in that thread shared you view of tubes being inferior to SS. Even an owner of your phonolinepreamp was (and still is, I believe) using tube amp. Yes, some preferred your phonolinepreamp over some other models of tubed designs, but the opposite was also true.

>I reserve my opinion about the Essential 3150 quality sound reproduction against not only the Aesthethix one but about any other phonolinepreamp. This not belongs to my targets and I'm not the right person to do it because the Essential 3150 is an important part in the José and my life and we could have some bias in favor of the Essential 3150.<

I have also found your comment above in that thread. Looks like you have changed you mind regarding:
“I reserve my opinion about the Essential 3150 quality sound reproduction against not only the Aesthethix one but about any other phonolinepreamp. This not belongs to my targets and I'M NOT THE RIGHT PERSON TO DO IT .......and we could have SOME BIAS in favor of the Essential 3150.“ (my emphasis by capitalization), since then!

Dear Raul, I read your post of 4:51 PM on March 19.  In that post, you merely quote your earlier post.  What am I supposed to take away from that?  Your post prior to mine seemed to say that you match discrete transistors in order to create the balanced circuit in your Phonolinepreamp.  I responded that it must be very tedious to match transistors for a balanced circuit, by hand. I now realize that maybe you were saying that you DO use bipolar transistors (which contain two very closely matched active devices in one case) but that the ones you use are specially selected for you by a lab at Mexico University.  Is that what you meant?  And why should I think that this makes the 3150 unbeatable?  Why must you then also throw in the insult that my system is not good enough for the 3150? You've evidently sold units to others with tube amplifiers, if that's the kernel of your disdain.

Dear @dover : I think you are a masochistic man and return for more, my pleasure.

I never did a 13D review. That aluminum way resonant dedicated headshell is a mess and never used because I had my tonearm prototype that comes with an outstanding one. The picture where is mounted was used too on the sale listing and that tonearm ( Sony. ) was the one on hand ( out of work. ) to made that.

Thank's for your invitation to move at " your level ". No way my friend I was there around 20 years ago but I learned. Go figure, after so many time you just are " touching " the SS alternative but with very low knowledge from your part and maybe through your future audio life never can  really grow up.

Your frustrations levels are extremely high and every time that you come back for " more " you only are going deeper and deeper in that very dark hole where you " enjoy " your audio life. There is no single " point " where you can see the ligth in that hole.
Fine that's your privilege.

Come on dover you can't hit me. Stop trying through your posts, it's useless.

regards and enjoy the MUSUIC not DISTORTIONS,

Dear @lewm : Yes, that's what I mean. Was that University whom help us to achieve matched pairs because the ones we choosed was single bipolar devices. Before the matching task personally we choosed one single manufactured bipolar over several other different manufactured bipolars, as I said in my mposts not all bipolars sounds exactly the same even if measured the same.

"""  why should I think that this makes the 3150 unbeatable? """ I never mentioned that.

What I said is that even that the matced pairs in the MAT02 and MAT03 are good ones was not the MATs what I was looking for our Essential design. As I told you, ML choosed both MATs at the end of the 80s in my monoblocks. I knew it very well and I want it something better that fortunatelly we found out.

Btw, what sincerely makes the 3160 unbeatable is the whole design, the very fine details we care on it and of course its quality level performance.

Sorry that you thougth that I'm insulting on purpose your system, it's not that way. 

Look, why any one could wants to integrate in his audio system that kind of quality level performance only for the next system link " destroyed/massacred " that quality levels.?. Even that, any one with my unit in those tube systems heard it the differences for the better even that almost all were biased/equalized and accustomed for many years to the quality levels of tubes and a well designed SS item is way different and we have to try not only to understand it but assimilate it step by step: we have to re-set all what we are accustom to and start to understand the new medium. Just as when we start to enjoy digital sources.

There are many things that surrounded the SS great experiences but rigth now I have to give and answer to the audio dover's trainer.


Regards and enjoy the MUSIC not distortions,
R.
