Discuss The Viv Lab Rigid Arm


I am trying to do my due diligence about this arm. I am just having a hard time getting my head around this idea of zero overhang and no offset. Does this arm really work the way it is reported to do?

Cleeds would be talking about me.

As a frustrated intellectual he is unable to discuss the relevant issues regarding this arm as he is unable to understand them. He is also unaware of and unable to understand my real motive

Ad hominem argument - the laziest of logical fallacies. You’re not fooling anyone here.

The magnetic oil film helps to prevent any bouncing from the needle to start

resonances but as you know that oil is not compressible there is no floating at all.

Oil is not compressible but it will displace.  Is there any movement in the arm in a direction beyond the lateral and vertical?  

It has always been my thought that simply using TAE as the sole figure of merit in this comparison is flawed since there are many other aspects that can make a 5° TAE of a 'traditional' arm soincally different than the same error on the Viv.

What Dave just said about TAE, and what I was trying to say early on in this thread.

All I know is that the RS LABS RSA1 tonearm violates every “commandment” of modern design:

underhung

not firmly anchored to plinth

cartridge DEcoupled from arm wand

unipivot

pivot is elevated above both cartridge and counterweight

CW dangles in space, free to swing due to LP eccentricity

And yet it works. By comparison, the Viv makes much more overall sense. Raul makes a fair point about the Viv website. There are many questionable claims on that website. You should see the RS labs owners manual. It is laughable. But that does not have anything to do with the results.

Crazy, isn't it? I think there are actually many examples of things in audio that at first glance (or even second, or third glances) wouldn't seem to work. I find it incredible the fidelity we can get from an LP today. I understand the mathematic fundamentals behind digital audio, for example (Fourier, Shannon/Nyquist), yet intuitively it still seems impossible to me.

What interests me about these underhung arms is exactly that - the geometry is contrary to what we've all "learned' is best practice, yet reports from those who've heard it are very favorable. That's worthy of further investigation because it suggests there's something in the current set of accepted best design practices that's either being overlooked, or over- or undervalued. Identifying those underlying factors could lead to better pickup arm designs of every kind, including conventional pivoted overhung arms.

There are people who lack a natural curiosity about the way the world works. For them, there is security and safety in books and policies and theories. But real discoveries - by which I mean both the great ones that change mankind and the small ones that can yield the greatest joy - are usually found in the real world through experience.
