Discuss The Viv Lab Rigid Arm

"IOW if the measurements are done properly they don't lie."  What is in dispute even among objectivists (and I don't like the word because it ignores that we are left to make subjective judgements even when we have objective data) is the definition of "properly", and who says that measurement X (or Y or Z) correlates with the sound of live music in a real space? Best we can hope for is a kind of consensus that evolves over time.

@rauliruegas I note you said I have a closed mind and am stupid. I am the very antithesis of a closed mind, that is why I am prepared to try things that break the normal convention, which appears to be the very opposite of yourself and @mijostyn, who are stuck in the world of dogma, theory etc. And as for being stupid, anybody that knows me would never call me that.

When it comes to closed minds I think you need to take a long hard look in the mirror.

As I said in an earlier post you and @mijostyn are 'The Handmaid's Tale ' of the audio world.

Ralph says above, "Drawing the line between what we hear and what we can now measure is likely to draw ire from both the subjective and objective camps. The very idea! But if you want to get down to knowing what's really going on, that's what has to be done. The acrimony between the two camps has to end."

I'm with @atmasphere on this one. I'd have been fine with sharing some thoughts on this if the conversation had maintained civility.

@mijostyn 

A tonearm has to be held rigidly in all but two directions rotation vertically and rotation horizontally.

How does the Schröder Reference and anyone who is a fan of it fit into this world view?

I'm not sure about the 'world view' bit. This is a mechanical engineering problem.

The arm tube doesn't appear rigidly coupled to its base (being suspended by yarn), so if vibration is present at the platter the pickup will be able to interpret the difference in motion as a coloration. 

Any arm that lacks rigid coupling between the arm tube and the base of the amp has this problem. How profoundly is a different matter but you can know with certainty that coloration will be present.

Of course the better the tt is suspended/damped to prevent vibration helps reduce this issue, but modulation on the LP itself will result in the arm not being perfectly in locus above the groove as it should be.
