What to listen for when setting VTF?

I've read that folks fine tune VTF by ear, so was curious what you listen for. How does more or less VTF affect sound? Thanks.

A good starting point is arm just slightly down from parallel in the back.

Also, bass will be very thin and lightweight. If the arm is to low, the treble will be recessed and light in detail. Bass will be "boomy" and bloated. I agree with the starting point a little lower than level.
