Agree on alignment methods, nothing to add there.
Regarding alignment though, in some cases, other alignments affect each other, just something to be aware of. The center of the record is more sensitive due to the smaller radius. But really, one thing to be aware of, is the "fancier" or more intense the stylus shape, the more important it is to have an arm that is adjustable.
But that's not what I was going to post about. I noticed on a couple other threads you have a static issue. Could it be something to do with that? It is a direct drive turntable, and the motor is right there in the middle.
I used to use a "Zerostat" gun for the general area, and a Cardas sweep record for the cart/system. Had lots of stuff but those worked the best. Static build up DOES have an effect on treble depending on the system.
