SAT 30K+$$ TONEARM: W O R T H T O H A V E I T ?


http://www.swedishat.com/

That is the everywhere touted and very expensive tonearm. Touted by all professional reviewers and obviously " satisfied " owners ( around 70 of them. ).

Here some reviews:

http://www.absolutesounds.com/pdf/main/press/AirForce%20III_SAT_HiFi+_0817.pdf

and you can look elsewhere the TAS one and others.

Obviously that the proudly owners started to buy the tonearm because those reviews and trhough audio shows but mainly for the " great " reviews.

It was ranked class A in Stereophile and I know are coming two new models that inludes a 12" tonearm.

Other than the very high price I never was interested on the tonearm design due that is totally out of my budget. Its price cost what a decent whole audio system cost.

Anyway, a few months ago in an other analog forum and through a TT review the SAT appeared in that discussion thread and was here when I decided to analize this regarded tonearm design where I found out that those 30K+ dollars are a true money lost and does not matters of what reviewers and owners think about where there are not clear facts all of them are extremely satisfied with the SAT.



Let me explain a little why I said that through my post to MF:


"""""""

from your Stereophile review the SAT specs are as follows: P2S: 212.2mm, overhang: 22.8mm, offset angle 26.10° with an effective length: 235mm.


Those numbers tell us that you are listening ( with any cartridge. ) way higher distortion levels, that you just do not detected even today, against almost any other tonearm/cartridge combination.


Obviously that the SAT needs a dedicated protractor to make the cartridge/tonearm set up but we have to analize what those specs/numbers has to say:

the SAT maximum traking error is a really high: 3.09° when in a normal ( Jelco or Ortofon. ) 235m Effective Length tonearm Löfgren A alignment ( IEC standard. ) is only: 1.84°

the SAT maximum distortion % level is: 2.67 when in that normal tonearm only 0.633

the SAT average RMS % distortion is: 0.616 when in normal tonearm only :
0.412 ( Löfgren B even lower: 0.37 ).

All those makes that the linnear offset in the SAT be 10mm longer than in a normal tonearm ! !

All those are facts and you or Mr. Gomez can’t do nothing to change it. Pure mathematics reality.

You posted in that review: """ Marc Gomez has chosen null points of 80 and 126mm instead of the more commonly used 66 and 121mm. """

that’s a deep misunderstood on tonearm/cartridge alignment input/output calulations in the overall equations used for that alignment:

NULL POINTS WERE NOT CHOOSED BY MR. GOMEZ BUT ARE PART OF THE OUTPUT DATA ON THOSE ALIGNMENTS CALCULATIONS.

In the same is not true your statement: """ the more commonly used 66 and 121mm. """

that " commonly " just does not exist and only depends of the standard choosed for the calculations.

There are several other things in that SAT design that not only are not orthodox but that has a negative influence in what we are listening it:

he said that the tonearm owner can change the bearing friction levels and this characteristics could tell to you that’s a " good thing " but it’s not but all the way the opposite because makes not a fully 100% steady bearings.

Ask you a question?: why the best top cartridges use cantilevers of boron and not carbon fiber, it does not matters that laminated carbon fiber the SAT has.

Carbon fiber is way resonant no matter what. In the past existed cartridges with CF cantilever and sounds inferior to the boron ones. ....................................................................................................................................................................... the designer was and is proud that the tonearm self resonance happens at around 2.8khz, go figure ! ! !. It happens way inside the human been frequency range instead to stays out of that frequency range. """"



Dear friends and owners of the SAT: way before the mounted cartridge on it hits the very first LP groove and against any other vintage or today tonearm you have way higher distortions that per sé preclude you can listen a real and true top quality level performance and does not matters the audio system you own.


What we can listen through the SAT is an inferior quality performance levels with higher distortions. Obviously that all reviewers and owners like those heavy distortions but that does not means they are rigth because and with all respect all of them are wrong.


Some one send the link of what I posted to the SAT designer and latter on ( I do not knew he read my post. ) I ask for him for the information about the effective mass of the SAT. He gave me a " rude " answer and did not disclose that information that in reallity was not important in that moment.



I have to say that at least two professional reviewers bougth the SAT tonearm., both with the Continnum/Cobra TT/tonearm. At least one of them say the SAT outperforms the Cobra one ( maybe both, who knows why bougth it the other reviewer. )

The credentials of the SAT designer are impecable and really impressive ones but no single of those credentials speaks about audio and certainly not on analog audio.

He is a true " roockie " enthusiast ( and I say it with respect.) and obviously that is welcomed in the high-end " arena/area/ring " where all of us are learning at each single day. Any one that’s marketing an audio item has a true merit and this is not under discussion: SAT designer has his own merit for that.

You that are reading this thread permit me to ask: what do you think, overall, about?, at the end audiophiles are the ones that has the last " word " or should be that way.


Regards and enjoy the MUSIC NOT DISTORTIONS,

R.

You said that you find it hard to believe that there are no other competitor that is superior to the SME 3012R. There are loads of great tonearms that are far superior to the old ’war horse’ SME! ( SME themselves have stated that the old design is superseded and surpassed by all of their new arms). On another forum, there is a major love fest for this arm...because one of their ’guru’s’ has stated that it is the best, LOL. I used to own this arm,and I can tell you it is nothing special at all! Currently, the only thing going for it is the price it can be had for on the used market..and with good reason. The arm chatters on its knife bearing, it looses information at the arm/headshell junction and the cabling and connections are a joke.
Take all of this and compare it to one of todays current top arms...like a Basis Superarm...and the old ’war horse’ SME 3012R heads straight for the bin.

@downunder

That friend of yours who owns the AS 2000...does he happen to get a little advise from this very same ’guru’, LOL...or does he just use his own ears...hmmm.LMAO.


@moonglum

indeed there are a number of disciples on that forum.
Many of them have never even heard the SME3012R arm, but that doesn’t stop them from wanting it, lol.
A’philes are well known for buying with their eyes vs their ears. Or better still, if some guru tells them it’s great...well then why bother listening for oneself!
@lewm

There is a supposition being made here...and that is the user who reports that the SAT is less satisfying than his SME3012R arm is actually listening to the SAT on an appropriate platform and with the correct set up of the SAT arm. Somehow, I seriously doubt it!

The SAT has far more going for it in the area of engineering than the old ‘war horse’ SME. That, plus the fact that the SAT arm has fresh cabling and connections...and I think you can see that to say you prefer the SME...would indicate that something is seriously wrong with your SAT set up!

i recently heard a great new arm from Durand...looked a lot like the SAT arm, and it was exemplary. Not saying the Durand is designed with the same flaws as perhaps the SAT incorporates, but the Durand was certainly in a totally different league than the old SME!


@rauliruegas



Agreed, with the SME3012R, the main problem does lie with the chatter induced by the Knife edged bearing. However, the removable headshell does present problems. While it allows for more flexibility with cartridge selection and experimentation with different headshell materials.IME, it also introduces some fairly severe losses at the arm to headshell junction. This, along with the bearing problem,means that it is a tonearm that has long since been superseded by numerous other designs. Too bad that some a’philes are going down this old SME path and not hearing the severe negative  impact that it is having on their systems.
@jeff1225 

you are assuming something....that something is that the fellow who is using the SAT and comparing it to his his SME3012R is using the SAT on the Air Force One...
@ halcro.


obvious to anyone once they hear the losses with this set up (SME removable headshell) vs. a well designed fixed  headshell...YMMV.


@rauliruegas 

Raul, no one has stated that there are no good removable headshell designs...however, if all else is equal, the loss at the removable headshell junction to the arm is going to be a factor vs. the one piece headshell with no wiring junction at that point. Ideally, the cabling should go all the way from the cartridge to the phono stage...with no breaks. 
What I am discussing here is the old war horse SME 3012R headshell design...not other far more sophisticated designs. The DaVinci made some extra effort to minimize this problem....the old SME design did not.
@jeff1225 If anyone is a complete idiot it’s you...you couldn’t even figure out how to scroll down the page!
Tango compared his SAT to his SME on his AS 2000 table, not on his Air Force One! This is when he came to the conclusion that he liked his SME better...on the AS 2000 table...That is the photo that you are looking at ...if..you could figure out how to scroll down the page, lol. Get a clue guy...and get with the picture, and stop trolling!

ok your turn now...idiot.
@jeff1225 look at my link again... this time scroll down..  or are u just trying to troll.:0(
and the system owner posted that he will change one SAT for the terrible double knife bearing design
SAEC 506/30 that I owned. This is double knife when the 3012 is knife/gimball.

Which kind of advisors has Tango and some of the other gentlemans posting there?

+1
Raul, that’s a great question, lol. But you may not want to know the answer!
@halcro 

Stop trolling yourself. You know we have had the discussion before...and you are dead wrong. I asked a mech/ structural engineer about the “moment connection” of a solid one piece headshell vs a two piece removable headshell...and as you will find out, the structural integrity of the one piece headshell is superior....in all instances,. Go and ask a mech/structural engineer this question, as I am certain that you are not one...after your ‘bs’ response above, and on the other forum. 
So Halcro you are an architect...or maybe just a ‘draftsman’...lol..
Your understanding of structural engineering tells me everything I need to know,...
i think you need to go back to school...and ask the teacher about this subject...and be prepared to learn it...and not just google stuff..

 
You sir are a complete idiot.
@rauliruegas

I understand that you are translating into English and then posting. Unfortunately, you are perhaps either misunderstanding, or simply missing some of the insults that are being thrown out there towards myself and other members. As an example, the word ’troll’ is an insult. There are always posters who immediately begin insulting others IF their opinions of the gear that they favor comes into question! We have seen that on this forum and on other forums as well. While i agree with you that the most prudent thing to do is to " turn the other cheek" , that is something that I and many others are unwilling to do IF the moderators do NOT step in! Luckily, on this forum, the moderation is good and as such, i rarely have to respond to the ’ad hominem’ attacker. But, occasionally, there is a post that slips through...like all forums.

As to expanding our knowledge base, that goes without saying. All of us can always aspire to that...
Also, remember this....your music may in fact be someone else’s distortion...and those that you might consider to be an expert, others may consider to be a neophyte.Please think about that before reposting your reply.

@lewm please don’t try and put words into my mouth. What I posted was an agreement with your inquiry to Raul. I failed to understand the point of his post.
I’m not trying to insult Raul either, I was questioning his post and the meaning behind it. Seemingly, as were you...which is why I posted the +1. 
My subsequent post to Raul about one man’s ‘expert’ is another man’s neophyte...is a common point in numerous areas of expertise. IME, it definitely applies in this hobby as well. Personally, I feel that there are a number of highly dubious characters in this industry at the present time....not a good thing, imo.
Again, don’t get me wrong, there are also a number of great people who have tremendous knowledge...unfortunately the dubious characters are getting more press these days.
