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?

To summarize,

A Cart' that is very familiar, used with a change to the Systems Amp's and New Speakers to was noticed to be a tiny bit off.

Same Cart' assessed with familiar Amp' and New Speakers, was still assessed as being  a tiny bit off.

Vinyl Source compared to CD Source for the first time in this home on both above systems, was notable for being near as impressive as Vinyl.

All attendees inclusive of system owner was on board with the commentary about the Cart'.

Both Sources, inclusive of the variety of CD Sources performed in a very very attractive manner.

My conjecture is that a Cart' that is a Optimally aligned Cart', as a result of going beyond the typical methods to set up, does has a noticeable X Factor, but when the X has seemingly been removed, the Cart' remains thoroughly impressive.

Maybe the importance of the X in the listening, is the easy to detect condition when the X has seemingly been removed?

More Importantly the priority is at my end, to enjoy the entertainment that is on offer in the Company of friends and fellow hobbyists, which I suggest some would struggle with as being categorised as an Audiophile.     

@lewm : Strain gauge needs correction too. Its amplitude developed curve does not coincide exactly with the RIAA one.

Anyway, if he does not shares his idea how we can comment about or better yet: how can we learn on it ?

Problem with LP is the tracking distortion developed by the stylus tip surface friction during playback. .

 

R.

Raul, I agree that a strain gauge used without any correction would not conform well to RIAA, because it would not be correct in the region 500Hz to about 2kHz, where the RIAA curve has a plateau. But like you said, because we don't know the identity of the cartridge, or even if it is a strain gauge for sure, I felt that no further comment was justified.

Friction is unavoidable, even the lowest coefficient of friction achievable is friction.

Surfaces have imperfections, the contact of Two Surfaces imperfections when movement of surfaces is occurring causes the imperfections to deform as they rub onto each other.

Such minute movements on both surfaces and the resulting energies produced, are the suspected cause of Friction.

As the fundamental cause of Friction is not quite known, some producers in relation to Cartridge design, have gone to the lengths of spending extra on making the Styli an improved smoothness to its surface by polishing to produce a surface with less imperfections. I assume with the intent to improve slippage of the styli as meets a surface that will create a drag affect. This will assist with Speed Stability, but as for improved extraction of data from the groove modulation ???
