Instability of the azimuth setting is precisely what turned me against the WT tonearm. My long time friend had a WT Reference. The tonearm could be seen to "roll" from right to left, changing azimuth all across the surface of an LP. I like to think this design flaw has been corrected in more recent versions of WT, like in the Amadeus, but I have never operated an Amadeus. I do know it is much loved. But that's one of the first things one expects of a tonearm; hold the settings stable. It's like saying you have a great turntable, except it doesn't hold speed.
