Fidelity Research FR-64 vs. FR-54


In a prior discussion, I had asked about tonearm suggestions for a Luxman PD-441 table that currently has a Denon DA-307 tonearm and Grado The Reference high output cartridge.  Many suggestions were provided.  A Fidelity Research FR-64 was suggested as a simple replacement.  I'm wondering if the FR-54 would also be good, being that it is mentioned in the Luxman manual in the same category as the Denon arm on there now?

Dear @lewm :  """ his nearly crazy hatred of tubes. """

No, I don't loose my time on something like " hatred " that in any circumstances ( in any subject or scenarion. ) affect my health. Human been nervous's system equilibrum is the name of a healthy life.

In the other side I already experienced the tube " massacre " to the MUSIC.

@lewm I know that tubes can makes " sond " but a simple piece of paper can do either and either my target and what I'm talking for years is not about " sound " but the rare experience of LIVE MUSIC through a home audio system.

That's the difference on what you and me are talking about. Certainly you need ( is a must to do it for any one. ) to experience it.

To that can/could happens is not a process of " one week to the next ". No, it's a long process because you have to learn step by step what to do and how arrive " there ". This demanding and learning ( with a lot of fun and frustations in between. ) beautiful process took me years not months where step by step I started to discovery the real and true NEW MUSIC/AUDIO WORLD that only whom are " there " can really understand.

thekong insist in that airborne high distortions in my system/room because he can't not onloy understand it but even imagine any system reproduction with out that ! ! !.  Is not his culprit, just can't understand it yet ? ? ? and if insist in that subject he will not ever.

@lewm , some of my friends here " refuse " to come to my place to listen  MUSIC ( in reality they come. ) because they told me that after they finished their last up-grade ( any kind. ) in their system and when they thougth that are " there " come and listen and they gone from my place with additional frustations that are their new challenge for the near future and I'm not talking of gentlemans that are audio rookies, some have tubes and other SS based systems.

@lewm life and everything in universe is changin every " second " and I think we have to change just for " fun ". Rewards are unimaginable and with NO-RETURN.

No one deserves to stay sticky where he is " now ". We have to move to enrich our day by day audio life.

Dear Raul, maybe I don't understand, but I am sure real expert like Mr J Carr must know. As I have quoted before, here is what he had to say on the subject (my emphasis by capitalization) :

BTW, I wouldn’t recommend combining the phono preamp together with the power amp. THE SOUND OF THE TURNTABLE IS TOO MUCH AFFECTED BY VIBRATIONS TRANSMITTED THROUGH THE AIR AND GROUND. FOR TOP PERFORMANCE THE TURNTABLE SHOULD BE IN A SEPARATE ROOM/CLOSET ISOLATED FROM THE VIBRATIONS AND AIR PRESSURE FROM THE LOUDSPEAKERS. If you were to go with a combination phono/preamp/power amp together with the turntable in an isolated room, the speaker cables would likely need to be v-e-r-y long.

On reply, you said the following:

Dear @thekong : Look, I never said that air borne does not produce vibrations/distortions. In the other side, I already did it that test.<

So, apparently you are claiming that while airborne vibration do affect others systems, your system is somehow immune to it! Problem is you can’t even come up with a theory on why that is so, let alone proving it!

Maybe, your room / system is so out of this world that physic works differently over there!

No one deserves to stay sticky where he is " now ". We have to move to enrich our day by day audio life.

So very true! Look at where you are, drilling on the same old things all these years!

You probably should stop living in a delusion!



Raul, Did you read my post from 3 PM today? In that post, I acknowledged that solid state devices can be put to good use in audio. Yes, the quote from the IEEE is an old one; I may even have posted it once before. When I come down adamantly on the other side, it is mainly because your attitudes are so infuriating, and I feel the need to be as dogmatic as you, only on the other side of the argument.  There may be people who read this crap and take it seriously, and I don't want anyone going off with a bad impression of tubes per se. Yes, for sure, I use a balanced differential hybrid cascode at the input to my phono stage, using the very same bipolar transistor that you use, or used to use, in your phonolinepreamp, as the bottom half of the cascode.  The MAT02.  It is very quiet indeed, but the main advantage is tremendous high gain. (The MAT02 has a transconductance of about 500 with only 10mA of current. No tube can do that.)  Because the gain is so high, I can anyway maximize signal to noise by keeping the volume control around 8 or 9 o'clock, where I even have enough gain for the Ortofon MC2000.  But keep in mind, the top half of the cascode, and every active device downstream, is tubes.

Like I also said above, if you want to lend me a phonolinepreamp, I would be pleased to audition it.  If you would just stop being a butthead about tubes, we could have other serious discussions.

By the way, please tell me about some of the revolutionary new transistors that are so radically different from what came before. FETs and MOSFETs are no longer brand new.
@lewm :  """  people who read this crap and take it seriously, and I don't want anyone going off with a bad impression of tubes per se. """

crap?, only for those gentlemans that don't want to understand the tube " crap " subject in 2017.

Here in México people say: " that the worst deaf man is the one that does not wants to hear "  and " that the worst blind man is the one that does not wants to see "  . Whom are you?. I want to think neither because one thing is that you like ( you have no alternative because you don't want to change: yet. ) to defend what you have and the other is that you have high ignorance level that I know for sure you don't.


""  using the very same bipolar transistor that you use, or used to use, in your phonolinepreamp,  """

wrong, I never used the MAT02/03 in the Essential. These are very old Analog Devices items and very good ones. As a fact those devices comes in my ML monoblocks ( this amplifier design I think is unbeatble even today. It's a " electronic lesson for any one. ).

No, we use " discrete " single matched bipolars that we choosed in between more than 10 different bipolars in the market. 

""  if you want to lend me a phonolinepreamp "", 10 years ago maybe I accepted not today. 

Not today not just because I " don't want it " but because first you have to take actions to move on where you are. If your attitude to do nothing but only critics with out real foundations living sticky in that " crap " you never grow-up and certainly I can't borrow my unit.

Things are that I can see that almost none wants to do nothing to enjoy MUSIC and it does not matters what you think about.
Yes, I know that you think that you are improving your analog experience but in reality you are only walking with back-steps and side-steps but improving: NOTHING.

@lewm : wake-up. You are in the road of a Formula 1 race " improving " your cicle/Honda Civic to compete against the true real F1 cars ! ! ! 

Why is so dificult to you and other people to understand it. You are trying to compete in that F1 race with a car of the Fangio times against the today top car technology.

It's RIDICULOUS for say the least. The name of the game in audio is: MUSIC and that'0s why exist all those net forums: to learn about as we learn here in Agon.

Regards and enjoy the MUSIC not DISTORTIONS,
R.


Dear @lewm : Do you know how after several years arrived where today I'm?:

some day ( and after that I continue with the same questions. ) I thougths:

what if all what the AHEE teached me and that I learned and living with is wrong?  where all those " wrong " audio subjects are? how to change and test these changes'?  and I took seriously all those and other questions and took ( I'm still doing. ) several actions. I'm not married in any way with audio but with MUSIC and nothing less.

Please do it a favor and ask your self something simple:

what if all those Raul's " craps "  are true?

I still make me questions as: what if I'm wrong in " this " or " that " ?

This is the attitude with we can really arrives " there ".

Regards and enjoy the MUSIC not DISTORTIONS,
R.
