Thanks for your inputs...
The fact is that as I said with ALL the SME models if you play a non groove vinyl always the arm goes to the center of the spindle so this cdr test is not valid, even it is not a clue. I also said that a/s force is added into the grooves and if you have no grooves you can't evaluate anything, this is the reason of the a/s tracks in some vinyls like Hifi news test record I have.
As Stringreen said before a/s is constantly changing but you should try to get the best sound possible, at least in my system if I change the a/s force I lose everything
