Discuss The Viv Lab Rigid Arm

Dear @reimarc : Well , I will no drink to that and let me explain what I posted.

"  how do you actually know what exactly is encoded in the LP grove? Unless you have the master tape side by side.  "

I never posted that kind of statement what I posted is that my target is to stay nearer/truer to the recording and I posted too that to reach or been close to that target weneed that each kind of system developed distortions most be at minimum.

My take in whole audio MUSIC reproduction to have top MUSIC enjoyment is to try to have an equilibrium between your classic dogma 100% subjectivity that ( you

repeated ( some way or the other ) in your answer to me ) and objectivity that in this thread issue demands that the stylus tip be centered in the groove modulations.

In my target I reached it using that equilibrium when for one side objectivity tells that any one of us must use LT tonearms and I did it and through the time ( i owned at least 3 different LT and over 15 pivoted tonearms and over 150 any kind of cartridges with different cartridge motors andat least 7 different TTs ) my subjectivity ( equilibrium ) tells me that I had to change to pivot alternative to reach the rigth bass range and to do this the second best alternative was and is use the Löfgreen alignments that puts that stylus tip nearer to what the LT does: NO MATTER WHAT. The underhung just has not that "perfect "equilibrium, no it's not rocket science only common sense andnoIdon`t need those master tapes and if you or any one makes what me neither will need.

Yes, from my statements you are far away from the recording and overall wrong and not because I say so but because almost all of you have not looking for that way demanding equilibrium.

"I had to change to pivot alternative to reach the rigth bass range and to do this the second best alternative was and is use the Löfgreen alignments that puts that stylus tip nearer to what the LT does: NO MATTER WHAT. .."

That depends, doesn't it, on what a LT tonearm "does".  In your opinion, it's the elimination of TAE.  But the virtue of an LT tonearm could just as well be the elimination of the skating force. If you think the goal above all else is to keep TAE as low as possible, even if it means a significant increase in the skating force, then an overhung tonearm is just the ticket.  If the goal is minimizing the skating force, then an underhung tonearm is preferable, when choosing among pivoted tonearms. Also, one could argue that the overhung tonearm does not come closest to an LT tonearm at any point in its arc; only the underhung tonearm achieves zero TAE and zero skating force, at its single null point.  The overhung tonearm never gets near to the latter goal. Anyway, I apologize to anyone reading this thread.  I hope I and some others who appreciate the Viv have convinced at least a few of us to approach the issue with an open mind.

Can you provide a list of underhung arms you have experimented with?

Is there the possibility the Cart's Styli will have less wear from a Groove Side Wall when used on a Underhung Geometry Tonearm?

I ask this, as the anti skate is not required, hence the force that can be applied to a groove side wall, through Anti Skate Setting creep or inaccurate set up on a Overhung Geometry is no longer an impact on the Styli when used on a Underhung Geometry.

In relation to the value of some Cart's that are being purchased and mounted on a Tonearm, if a method used that is able to extend Cart' Life through lessened wear, and the TA > Cart' marriage is one the end user finds audibly satisfying. The notion that wear might be decreased, might be one more occurrence to add to why a underhung geometry is worth considering.  

Pindac, good question about stylus wear. We’ll have to wait and see; using theory, I could argue either side of that question in favor of either overhang with AS or underhang.
