I have found that when i lighten up the VTA i loose to much sound stage, 3d sound and image. I am beginning to believe that this combo is dependent on what turntable used. I had the combo on my Aries 3 set up, my UNIverse had over 1000 hrs on it and i was easily able to track in the 1.65 area with out any problems and had total enjoyment listening to music. When i changed tables to Redpoint i found that at those lower settings i was not enjoying the sound and music as well. I slowly started increasing VTF till i got in the 2.00 to 1.95 area and for me thats where i have VTF for the best sound to my ears.
As for VTA i start out as level as i can determine and make small adjustments from there. And bring the adjustment in by ear for better sound.
The higher VTF is much better for my whole musical picture, i dont think there is a rule but what actually works for you and your gear. You have to make your mind up that until you make changes in your set up you will never know if you can get better sound or worse. It just has to be in small movements because UNIvers is so good that as Doug says when you find that window of sound you will surely know it.
