Tonearms without anti-skate, damage to records?
Hasn’t Peter Ledermann testified to the uneven wear on styli he has inspected personally, due to radically incorrect AS? So there’s your evidence, presented by an expert witness. (I agree with you that there’s no such thing as a perfect amount of ... 
Shelter 501 mk2 v mk3
If output is different and internal resistance is the same, that implies there might be a difference in magnets used or the core construction Then there’s cantilever material and stylus shape; are those conserved between the two? A few years ago I... 
Vinyl static ionizers who's used them?
Benji, thank you for answering my questions, and I don’t see where I was confused. The questions I asked were based on my understanding of your original post. Many people have claimed in the past that the act of the diamond stylus rubbing against ... 
What is your to earl’s Maximum Distortion %?
Earl called. He said his views on tonearm alignment have been distorted.  
What Does It Take To Surpass A SME V?
As has been written elsewhere (by me), the effect of CW mass on total effective mass is equal to the mass of the CW multiplied by the (distance from the center of CW mass to the pivot)-squared. So you cannot just say that CW is 10% of total effect...

Benjie, you’re confusing us with actual data. I’ve been stewing on the question of whether or not to buy that Simco that you own and which I agree could settle all these questions. After nulling the charge in a hand held record, does charge reappe...

Jwall, my fallback position on the Acaia is that if it doesn’t work in my listening room, I can use it with our burr coffee grinder.

Actual science suggests that the static charge between the LP surface and the platter is unaffected by discharging the playing surface and quickly migrates to distribute over both sides, when you flip the LP to play side 2. This suggests you need ... 
Analog to Optical Converter?
Your record player has a built in phono stage that does RIAA correction and amplifies the signal from the cartridge. Yes?  
Vinyl static ionizers who's used them?
Antinn, I haven’t taken the time to look at your references but there are two types of these devices, so far as I can tell. One type works via electrostatic discharge. That’s the type that produces ozone. Humans should not be in the room when they...

I forgot to add that I would bet several of the expensive ionizers, if stripped of the cosmetics, would turn out to have a heart consisting of one of those $30 devices you can find on eBay or Amazon.  
Vinyl static ionizers who's used them?
Harpo, If you google "positive ion generator", you will note that they all also produce negative ions, and you can find on both eBay and Amazon simple devices that appear to produce positive ions on one lead and negative ions on another, usually d...

“It’s not good to run an ionizer continuously…” That cautionary note applies only to devices that generate ozone. The devices we’ve mentioned so far don’t produce ozone. On second thought, that plasma igniter might produce a tiny amount of ozone... 
Wayne's Audio Turntable Periphery Stabilizing Outer Ring
Clearthinker, with respect, how can a very short tonearm negotiate warps better than a typical longer tonearm? The effect of a warp on VTA would be magnified for a very short arm.

In that device, what keeps the positive and negative ions in the air flow from combining with each other before excess charge of either polarity that may reside on the target can be neutralized?
