I absolutely love my AT33PTG/II. Glad to see another AT33 + studiodeck user. Break in was very short for me, not much change since new but there definitely is an "opening up" period over 20 hours or so. Absolutely sultry sounding with nice detail and good bottom when called for. A great tracker too!
I also found that raising the back of the arm about 2mm or so really brought out some nice detail. I've read elsewhere the AT33 likes to be a bit "tail up" and mine seemed to be no exception.
Input impedance makes a difference as well. I will need to see what I settled on (200 or 470 ohms - as I recall these are my options above 100) but it needs a bit more than the 100 ohm recomendation otherwise its a bit boomy to me.
Wish I could help with your azimuth issue, but I remember it being REALLY fidgety to adjust as the joint moves when tightening. Did you receive two hex wrenches with your table? I don't remember which one it took but if you needed the large instead of small, I could see where that would lead to problems.
