Discuss The Viv Lab Rigid Arm
Raul, I have more or less done such experiments already. The only way to get any null point on the playing surface of an LP, with the Viv or any other tonearm that has zero headshell offset, is to mount the tonearm with underhang. If you mount the...

The cause of friction is gravity, in this case..

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 ident...

Pindac, in your recent very long post, I am not quite sure what you wanted to say, but I take it that you believe the pleasure of good music enjoyed in the company of good friends is the highest goal of our hobby, and who could possibly disgree wi...

Must be a strain gauge cartridge. It’s not a matter of simply removing offset. The stylus tip must also underhang the spindle. You don’t want one without the other.  
Coil vs. Cart impedance
To be specific, "impedance" is a frequency-dependent reading of resistance.  The impedance is different at different frequencies, so to be completely useful, the frequency or the range of frequencies should be stated, but most often is not stated....

Just to note that Tom uses the term zenith and the term headshell offset angle as if they were synonymous. For me, and in all my comments above, the term Zenith is used to refer only to the angle of the mounting of the stylus tip in the cantilever...

 “On paper” your cartridge should be loaded with 500 ohms or higher. However, whatever floats your boat.

It would seem to me that the skating force does much more to prevent the stylus from being “centered in the groove” than TAE. AS is all we have to counter skating but AS can only be correct at one or two moments of play, because it’s constant in m...

What if the issue is skating force?

This is the 3rd thread devoted to the wonderfulness of Andy Kim.  Just saying.  
Technics SL 1200 GR
If it’s P3 vs GR, go with GR. You’ll be satisfied for years to come. Or even vs P6.

No RIAA correction?

I am saying that inspection by a competent disinterested professional third party is what I would require if I were to buy a pre-owned megabuck cartridge. Speaking for myself only. I guess you don't agree, and that is fine.
