VPI 2nd Pivot for 3D

Raul,

I am having an extremely difficult time comprehending your message. Extracted from your last post is the following example:

" Your " facts " about can’t prove that I’m wrong in my main " at micro levels unstability in any unipivot tonearm ". Reason is that those measures were not made it to prove it but to prove other targets.
We have to know what kind of measures where and how to achieve it to prove a specific subject. This time: at micro levels unstability in unipivot tonearm designs."

I have no idea what you are trying to say here. Really I am at a complete loss. Would you try again?

It seems you are trying to make some point about instability due to wobble, but it is not clear to me what it is. Moreover, it is entirely unclear to me what the practical consequences might be? If it is to make the point that unipivot arms sound different than comparable double gimbal arms, I concede the point. But, we must also acknowledge that two different double gimbal arms sound different from each other too. Where does that lead us?

Dear @cleeds : Good that agree with bill. I that regards are wrong because the Bill's facts/tests were not created to measures the stability in tonearms subject. So in this regards means nothing.

I'm not talking if you love unipivot kind of sound or if you do not, this is not the MAIN SUBJECT but its inherent unstability.

You said: """  that make them inherently flawed is just nonsense. """
but you did not say why is inherently flawed all what I posted .. Through my posts in this thread I explain those facts in a wide manner, read it again and please please come back here and tell us the why's of that " inherent flawed ".

 You followed:   """  There are reasons that unipivots endure in the marketplace... """

As several other audio " myths " is only because ignorance. Almost all audiophiles are focus on what we like and not in what SHOULD BE that is where lives the MUSIC and the audio hobby.

That " should be " is something that each one of us have to make and take a day by day learning path where in many audio/MUSIC subjects on that whole " should be " are almost unknow for many of us.
Not an easy process task that it's not only time consuming but dificult to understand and where we need to ask our selfs: what is happening down there, at each single step that any audio link makes its job. 
In the case of the ridding cartridge job almost we have to analize as if we were the cartridge and have the vision of " our " job ridding those tortuos LP grooves and all what this means. We have to do first with out taking in count TT or tonearm but as a stand alone cartridge and from here analize what in the " hell " are the cartridge needs to fulfill its very hard task.

It's an overall process at each step, we have to go as deepest as we can with patience.
We have to analize at least from where comes the recorded information in the LPs. Well, that normally comes from what the recording microphones pick-up in NEAR FIELD not at 30 m. from the music source as happens when we are seated in a music hall.

Those are incomplete examples to sooner or latter know how everything in audio SHOULD BE and improve our listening quality levels.
The rewards are fenomenal and we learn several things as if we discover a new audio world.

When we start to make the audio systems changes to achieve that " should be " we will know that in the past we were wrong and in this " new world " we really enjoy the MUSIC as never before.
I'm still in the quest to finish that " should be " and I can tell you that's worth to do it.

I'm not different of each one of you: I'm a MUSIC lover and I want to achieve the true best listening experiences through my home stereo audio system. Tha's all and as many other audio items unipivots can't help to approach that targets.

Regards and enjoy the MUSIC NOT DISTORTIONS,
R.

"I imagine myself as the cartridge tracking the record and I thereby know unipivots cannot work"

hmmm ...

That's a fair summary. I would only add that Raul asserts his claims as "facts" and when pressed for proof, basically just repeats the assertion. Yet he demands rigorous proof from anyone else who cites a fact. So it's impossible to have a meaningful discussion with him, which is why I've given up.

It's plain to see that Raul is wrong about unipivot pickup arms. I share his distaste for them. The difference is only that I consider it a preference. I'm not trying to convince anyone that "facts" support my preference, or that I have some special understanding of how they function.

Perhaps this post is a progression too far, but may I suggest that we agree that there is no one, single, absolute "right" way to do anything in audio. That is true for every aspect from tonearms, to amplifiers, to speakers, to wires...whatever. Each of us has preferences in equipment, music and so forth. Accordingly, looking for "proof" of something like this is somewhat analogous to the search for the Holy Grail.
