What angle should I set the VTA on my VPI turntable?


I can't believe after all these years, I am asking such a basic "analogue 101" question, but here it goes. I own a VPI turntable that has a "VTA on the fly" knob.  I thought the best VTA setting was for the arm to be 100% parallel to the record surface.  

However, based on some research, I am not so sure that is correct way to set the arm to achieve optimal VTA and correlatively, optimal SRA.  Not sure, ... but I think I have to raise the pivot side of the arm.

Any advice would be appreciated. 

Thanks.

Kleos (and every Lyra I've owned) should start with arm tube level and parallel with record surface with stylus playing.  Then turn the VTA adjustment knob one full turn up and listen.  Then back to level and listen, then one full turn down and listen.  Return to parallel with record surface and listen.  Whatever sounds best, adjust to that position.  Then use that as a starting point to repeat the process.  

At some point, moving the arm pivot up or down one full turn will degrade the balance, timing and imaging.  That means you've gone too far and should start heading in the opposite direction.  

Just as a reminder, tracking force may change slightly with VTA changes.  Check the rest of the alignment during the testing to make sure VTA changes haven't change them.
