Discuss The Viv Lab Rigid Arm

I made an error in my post of 10/27 at 3:10 PM. The TAE of a 9-inch UH tonearm would not range between +9 degrees and -9 degrees, while passing through TAE =0, because the radius of an LP at outer grooves vs inner grooves is so radically different. Because the radius at the inner grooves is much less than outer, making for a tighter smaller circle at the innermost grooves, TAE at inner grooves would be higher than it is at outer grooves, even when you align for a null at the midpoint of the playing surface. That consideration is what leads to the very complex equations for TAE derived by Lofgren and others. You can see this easily in the graphs posted above by Intact Audio (Dave). John Ellison posted graphs showing TAE for a 16-inch UH tonearm over on VA, perhaps included in the thread I referenced.  His graphs also show the effect. This is why the template for the Viv puts the single null point nearest to the innermost grooves, 90mm from the spindle. 

@lewm  and dear friends: Maybe many VIV owners not even who is J.Ellison and they need to find out that information.

Now, . Ellison posted in your link about the underhung Yamaha yonearm in the thread you started there, so it's an answer that he gave to you:

" The Yamaha straight arm is absurd. "

 He posted too something that I posted several time about my personal targets:

" I don't really care what it sounds like. I care only how it measures.

In other words, I want an audio system that will accurately reproduce the sound of the master tape. If additional distortion improves the listening experience, then I want that distortion added to the master tape. I don't want my audio system to add distortion.  "

His last statement/sentence  is my target but all what he said is just a true fact for people as mijos or me.

An his last post in that thread in different words is something I already posted here and from year now in several threads:

" I firmly believe that the people who prefer vinyl also prefer distortion.

It's really quite simple. If you have a reference recording and you make a vinyl copy of it that sounds different from the original, the difference is a result of distortion. We all know that vinyl sounds different because something can't sound better than something else unless it also sounds different.

I've made hundreds of measurements of vinyl test records and I know that the vinyl format produces significant measurable distortion. Therefore, I have no doubt that I'm listening to distortion when I listen to vinyl. That's what gives vinyl its distinctive sound quality.

Best regards,  "

Btw, that's why we " say " ( not me )  that vinyl has superiority to digital when it's theother way around. No pun intented.

lew, I really appreciated your link because that gentleman confirmed several of my posted believes in this forum.

I am as familiar with JE's views as I am with yours.  Why can't you just go your own way, with my blessings, and know that there are other humans who think differently, on many matters related to audio, at least?  Like JE, you are replacing my comparison of the Viv tonearm to other conventional pivoted tonearms with a comparison of vinyl to digital.  I certainly readily concede that vinyl has more of various distortions than digital.  Happy?  Further, JE is calculating "distortion" using formulae that incorporate TAE as a determining parameter of distortion.  This is what is called a tautology.  Of course, if you make TAE a factor in the equation for distortion, then you will be finding that the more TAE, the more distortion. Like I also wrote above, in an earlier post, JE admitted that he liked the SQ of the RS Labs tonearm, based on LISTENING to it. 

Btw, I know for sure that you as @mijostyn  , me and some other gentlemans just do not like to add distortions in any way and nowhere our room/systems.

I posted several times and I 'm sure that at least one time you read what I posted:

" the name of the MUSIC/sound is to put at minimum any kind of distortons developed by our room/system: this is my main target that even what I posted several times too: nearer to the recording target.

Vinyl has emotional and sentimental ties to the past. It is also a lot of fun. For most people digital is rather boring and they assume it is lifeless. Great digital recordings are stunning and once you get into digital signal processing and all it has to offer the fun is also restored.
