jtimothya, you do not do yourself a favor when you use terms like, "sonically astonishing." The difference between "Power On" and "Power Off" is "sonically astonishing." A degree or two of arc is not. I am sorry that you spent so much on the Feickert but the DB systems protractor is less than 1/2 the price and twice as accurate because due to it's geometry it magnifies the error allowing you to see it easier. It is a little finicky to use but once you get the hang of it it works brilliantly and on any tonearm and cartridge. The trick with the "landing spot" is to use an awl and put a little indent in the circle to keep the stylus in place. Not to large or it will swallow the end of the cantilever. I also put a dab of low viscosity cyanoacrylate in the indent then quickly wipe it of which stabilizes the indent so it does not get progressively larger with use.
