Genez, Many others have noted, and I agree, that using a groove-less LP may be a good way to demonstrate skating but it is not useful for setting AS, because in real life the cause of the skating force is friction in the groove. Friction on smooth vinyl is different in magnitude. So one should not set anti-skating to oppose skating that is observed on smooth vinyl.
Does removing anti-skating really improve sound?
I know this topic has been discussed here before, but wanted to see if others have the same experience as me. After removing the fishing line dangling weight from my tonearm I’m convinced my bass and soundstage has opened up. I doing very careful listening with headphones and don’t hear any distortion or treble harshness. So why use anti-skating at all? Even during deep bass/ loud passages no skipping of tracks. Any thoughts from all the analog gurus out there?

lewm ... in real life the cause of the skating force is friction in the groove ...We have been down this road before and you are mistaken. Clearly, you are confusing cause and effect. Consider a properly aligned true, tangential, straight-line tracking pickup arm. Its stylus has friction in the groove, just as a pivoted arm. But the straight-line tracker is not subject to skating force. The reason for that is that the real cause of skating force is the offset of a conventional overhung pivoted arm. A consequence of that offset is indeed friction created by the stylus in the groove. But again, that’s an effect - and not the cause - of skating force. Consider also that the same exact cartridge will have different skating forces if installed in two substantially different pickup arms. That’s because the greatest factor in generating skating force is the arm, not the stylus - although different stylus shapes will result in different skating forces. |
larryi This issue has been raised with a number of cartridge manufacturers and I don't know of any who endorse not using anti-skating.VPI is not an advocate for the use of anti-skating. |
lewm and especially pegasus, right on. This is another one of those things that looks simple enough in theory but gets complicated fast in practice, mainly because in theory everything is static when in reality everything is dynamic and constantly moving. The blank record demonstrates skating but can't be used to set skating force because its blank. These forces are constantly changing depending on groove modulation. Then they change even more when the whole record is going back and forth, which it always does, because the spindle hole is never perfectly in the center, on and on. Good call pegasus catching what no one ever mentions, damping. Even Fremer never mentioned that, and he never misses anything! Good one! I'm a little surprised at not hearing any difference with my arm. Well not that surprised. It was a real quick and dirty test. The Conqueror uses the fishing line with weight method. I simply moved it so the line wasn't going through the hoop and sat the weight down. The loop the wire goes over, the adjusting rod, all of which for sure is vibrating and messing things up when a record is playing, all that was left in place. The way I see it, if I hear a big improvement like tubelvr1 heard then the rest comes off. But it better be worth the extra stylus wear too. And it wasn't even close. So pretty much like I thought- there's so much difference in design and implementation that you just can't get away with blanket conclusions. Does removing anti-skating really improve the sound? It depends. |
