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.

Dear @genesis168 : Measurements always can be correlated with sound if we know what to look for and how to do it.

Through the AHEE all we " learned " that subjectivity is the name of the game but this was and is for convenience of that AHEE.

Today what measures good sounds good, in the past things were way different. Today audio designs achieved a very good grade of maturity in almost all orders.

In many ways the AHEE accustomed to like more what is " wrong " than what is good and they teached us with no single explanation/facts other than : " listening is bealieving or I like it ", no matters what.

I'm not against the SAT, every audio newcomer is always welcomed, no doubt about but there are not very clear information on it. That's all.

Dear @tli @jareko SAT’s owners: """ The sound was not as good. They are dim and flat when compared with SAT one..... """

I seen no apparent reasons for that kind of bad quality performance.

Now, the SAT choosed alignment is a custom one that " plays " inside its own " rules " and if we want to test the SAT with the standards as Löfgren A or B then we have to play inside those standards alignment " rules ".

I think that all of you have a universal protractor with standards kind of alignment and all of you can make some tests changing the SAT custom alignment to one of those standards alignment preserving some parameters.

My advise to all of you is that do it using the " normal " protractors you have.
To do that you have to start changing the P2S distance where you have the SAT rigth now for the tests goes according the standards alignment " rules ":

for Löfgren A/Baerwald ( IEC. ) the P2S is: 217.36 and for Löfgren B ( IEC. ) is: 216.86mm.

@tli your smart tractor is useful for the P2S distance. Now, if you made those tests where you found out a bad performance and did it changing the P2S distance then try a new intent and obviously listening to LP tracks you know extremely well.


I hope that the SAT headshells slots permit the new offset angle that has advantages over the 26.1° in the custom alignment.

I’m taking my time with the SAT because I always try to understand what is happeniing " down there ". Unfortunatelly I don’t have the SAT " on hand " to make those tests but all of you have it and those tests will be really enligthing for all of you.

If the SAT/TT permit it and all of you have the time after that kind of tests you can try a P2S of 220mm. and " see " what happens.

Will be and is appreciated that you share those tests experiences with all of us.

Btw, any one of us can develops any kind of custom/dedicated alignment and the only trouble is to have a dedicated protractor for each custom alignment we want.

This thread is not to blame the SAT but to understand it and if I can help to the owners/audiophiles then that’s the main subject here . Maybe all ofg you already did it and then you just do not need any " help " about but maybe for some of you can be interesting to test it just for " fun ".

Thank’s in advance.

This is all you should have posted...

@jperry , no I don't have the opportunity to listen it yet and I'm not in a hurry. Better to wait not only for the new models but for a more steady/experienced designs.

Dear @advanced101: Obviously you are to " advanced " for me.

Your marvelous post was and really enriched the thread and other posts on it.

Thank's for your great contribution, as always was and is a learning one.

@rauliruegas ,

Great information and write up on something you haven't heard.

I will be looking forward to your next review of something you haven't heard.
