Tonearms without anti-skate, damage to records?

Dear @mijostyn : " 50% is WAY too much. "

I think you already read my post and like to post that " figure ".

Again, in those old times the advise was VTF/AS same value, latter on: AS lower than 70%, latter lower than 50%, latter..... but even today Ortofon recomend VTF/AS same value:

There is no proper amount of AS and that’s the problem. The AS set up today is innacurated. Again, each one of us choose our trade-offs. You like to set that innacurated AS good, no problem with me.

As you I don’t care to much about stylus wear on this specific AS issue but the quality reproduced sound level and what you are saying is that in a cartridge with 1.5grs VTF and with and AS of 0.15gr makes the difference. As you said: I have not compliant about.

I don’t know if you tested cartridges/tonearms with and with out that " 0.15gr. AS if you did it then you prefer that very low amount of AS against none and what you posted:

" Forget about hearing, too many psychological factors. "

Is applicable to any one including you and like clerthinker said: " imagination ". Nothing wrong with that.

@viridian  Not only I trow away but before me VPI too. 

@clearthinker , you know that was tongue in cheek and you and I agree on many things just not air bearing arms. 

Of course you do not need an antiskating device, not that your arm doesn't skate, it does, with air currents in the room, with changes in level, with different weight records, tension on the wires etc. It is impossible to predict. Much of this holds for any straight line tracker including the Schroder. Does any of this effect the sound? Probably not audibly. It is all theoretical in regards to sound quality. IMHO it all adds up when regarding the entire system. Simplicity is alway best, less is more. I regard Air bearing arms like I do ultrasonic record cleaning, like unnecessary complication and diversions. But, that is me and I am responsible only for myself and perhaps the systems that I help to set up. Here we share ideas even if they might be unpopular to some. Political correctness is only a way to prevent solving problems. Anyone can attack my feelings any time they want. They are already numb from years of self incrimination.  

I have little truck with political correctness.  The world has gone mad, led by the USA.  And now we have wank (woke), again originating in the USA.

The principle of free speech is far more important.  Wan**rs would have America and Europe become like Russia and China where you receive long prison terms in life threatening prisons for small breaches.  Breaches need to be extremely severe before I will censor.

@rauliruegas , you would never buy a VPI because like me you do not care for unipivot bearings.

There absolutely is a correct amount of antiskating even if the skating force is variable which it is, within a range and is mostly dependant on groove modulation and the shape of the stylus. You can see this easily if you watch the cantilever deflect. The goal is to set the antiskating so that the cantilever remains straight across the record which you can do and it works reliably if you have a good eye. As measured with the Wallyskater with the Lyra Atlas this turns out to be 11% or 0.11 times the VTF other suggestions are wrong to one degree or another. This will change slightly with stylus shape between 9 and 11%. 

I have a human brain like everyone else and are just as subject to psychological deviation as anyone. The only difference is I realize this is at play and take measures to neutralize it as much as is possible. Many of us here deny this is a factor. "Trust your ears." My ears or anyone's ears are the last things you want to trust. I really mean this. After all the theory and set up enjoy the fruits of your labor with your ears knowing you have done the best job you are capable of, to minimize distortions! Sound familiar? 

I have tested every cartridge I own to a patently ridiculous degree. I even built my own horizontal video microscope to make some of these observations. You can see it here https://imgur.com/a/9VcylFy  This is the set up for looking at stylus wear. The scope can be used adjacent to the turntable to view VTA and overhang. Those with a scientific background might recognize the staging mechanism of a medical microscope. 

Dear @mijostyn : No, I did not but that was not the issue why posted VPI and I would like to know what HW was thinking when designed his tonearm with out AS mechanism.

Now, yes I like to put at minimum developed distortions by the roomsystem and I like to do it when exist some certainty that in reality " those " distortions are at minimum but in the AS subject it’s a losted " figth " before that figth begin. To many variables and " if’s " . You ca't have certainty of any " thing " that is constanty changing alomost groove after groove all over each one LP grooved surface where does not exist two different scores in LP’s recorded exactly with similar groove modulations at the same places all over the LP’s surface. We can’t really know if distortions are at minimum with that AS of 0.15gr. against none.

For now I don’t like to " figth " in something that defeats me before I begin against it. Just my common sense on this specific AS subject.

You are fine with what you have and me too with what I have and maybe just maybe the quality sound differences between that 0.15gr and none could be inaudible at least in my room/system and yes with my ears.

For me and taking in count all what I posted about it’s futile/useles to worry about AS. Today I’m really happy not to have be worried because that imposible to fix AS, yes that’s me and my opinion.
