Thanks for asking a great question, Rich! The answers here have shown me how to get that little extra from my rb300/rega. I hadn't really been that concerned about tweaking this set up to the nth degree. To keep it short, I've gone back through this method for AS and found that the rb300 was dialed a little high, that is, enough to see a clear deflection. After correcting to get back to almost no perceptible diflection I tweaked it back up just a tad. It did make a small, but noticeable improvement in dynamics and clarity.
