What is you tonearm’s Maximum Distortion?

Btw, this is the scenario of SAT:

 

Tonearm Alignment Calculator Pro - Vinyl Engine

 

R.

@intactaudio : " manipulated numbers without disclosing the manipulation to justify someones choice."

" your proposed alignment simply "

 

and way before you posted the graphics I posted to you:

 

 

" that is the SAT tonearms alignment. "

Btw, was ridiculous/false/untrue/lie that in your graphic instead to write SAT use it my name when the alignment came from SAT and I posted to you before that graphic and you knowed.

 

" I do not believe he would fudge the inner groove radius to 75mm in the calculations "

 

that’s only your ignorance because you showed with this kind of statements that your knowledge level on the SAT tonearm is near zero. Your problem not mine.

 

""" Everyone is allowed their own choice of compromise """

 

Yes, that’s why exist the custom key in the calculators.

 

@optimize thank’s for your expert explanation.

 

Btw, intactaudio you posted that with the SAT the distortion level goes at 60mm to 2%. Well could be that your speakers goes even way higher that that figure and no compliant about. The phono stage you are using ( I think you are using it ) develops a huge distortion level with that high swing of 3db deviation in the RIAA inverse eq. and I can understand with out compliant because it’s what you are using and that makes more harm that the SAT alignment. Incredible that you made a " film of drama " on this issue.

 

In the other side all SAT owners are fully satisfied with Mark tonearms. I listen 3 times to the SAT and it’s really good and I think that @mijostyn did it and like it too.

 

I think that if your main undisclosed attitude is to hit me then you are wrong in that specific alignment issues that as I told you I’m only using it and whith not the kind of critics like you other than exactly the same opinion that @optimize about Stevenson A alignment.

 

So I appreciated if you take off my name in your posted graphics due that no belongs to it.

@intactaudio : " If the parameter manipulation is kept hidden then there is another term for it.. "

Well, don’t tell to me but directly to the SAT designer. The OP P2S 225.. was asking for better numbers and the SAT ones gaves it.

" I have found no point in listening to the last track ... "" that's at least untrue because the higher distortion happens only with the LP that has groove modulations  up tp 60mm ( inner groove ) and even that you don't know if could be aware of it due that distortion goes in increment or decreasing groove to groove and ears goes accustom to. Not easy todetct it. Don try to " satanize " it: bad attitude.

 

Btw, have you an alignment with no trade-offs? and if you don’t have it then maybe it’s the rigth time that you do it because you critic and critic but don’t give nothing in change. Yes, you are free to post whatever you want but could be bette to leaft to critic the standard alignments and show a no trade of alignment that we all can name intactaudio. Show something and stop critic because that critics goes not against me because I did not any alignment I only use it as all audiophiles.

 

Which tonearm/cartridge alignment are you using?

 

R.

@intactaudio : It’s only a parameter manipulation and that is the SAT tonearms alignment. At the end is not rocket science. Btw, Did you already test that kind of alignment?, I do and you can be " surprised " by. 

As Mark SAT designer says and makes sense:  " The null points for the SAT arms are located at 80 and 126mm. Ultimately, this was a choice of enjoying a consistently higher level of fidelity for 95% of the time over having less angular error on 5% of the tracks. "

Exist rules but to each one of us can be broken in favor of quality performance with MUSIC.

That alignmnet by SAT is wrong? no it’s only different and when tested each one of us can decide about. What you think or what I think is only that " think " as is non-important in the whole alignment game: it’s each one game not yours not mine.

 

R.

@intactaudio  : Yes.

 

R.

Dear @fusian  : You need two additional parameters to make the tonearm/cartridge set up and achieve those figures of lower distortion levels and that I don't gave you and are the null points that are: 80mm. and 126mm. not the one you are using today.

R.

@fusian  : Forgot that if you want lower distotion figures then and using Löfgren A alignments its tonearm parameters set up are:overhang  21.58mm and offset angle  24.8°.

Where the maximum error  0.94°   maximum distortion  0.33%  and average distortion  0.22%.  All these for your P2S  225mm.

Please don't ask how I found out those numbers because I have no time to explain you ( using VE calculator. ) or to any other gentleman, but that's it.

 

R.

 

 

Dear @fusian  : Around 90% of tonearm manufacturers used and use one of the 3 best knowed alignments: Löfgren A or B and Stevenson.

Those same tonearm manufacturers choose between different but " standard " tonearm efective lengths: 9", 10", 10.5", 11" and 12".

 

So run 5 times the VE calculator and you will know how measures the 90% of audiophiles tonearms. That's it.

R.

@fusian : Here the calculation. For a protractor you can contact MINT-LP and he will makes a dedicated protractor for your today TT/tonearm, ask him for Baerwald alignment. It’s really accurated and not an expensive protractor:

Dear @fusian  : I don't know which kind of alignment you are trying to use.

 

Löfgren A/baerwald ( IEC standard. ) gives you a little lower distortion levels : 0.61% and 0.4% respectively with maximum tracking error 1.78°.

Now, it's not easy to be aware of the true quality differences you are listening between that average distortion 0.73% and 0.4%. To be aware of it your room/system has to has a very accurated high resolution and " educated " ears.

 

Regards and enjoy the MUSIC NOT DISTORTIONS,
