@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.
