If a Linear Tracking Tonearm like the ET2 are set up correctly with table/stand being level there are very few ajustments after the initial setup, I have had my ET2 set up for over a year and have only had to adjust it once just last week. Most tables need an adjusting every 6 months just to keep it right (if you use your table alot). I had an Linn LP12 that their was always something to tweak on it and I messed with this more than my current setup that's why I switched to the Teres 255/ET2/Shelter 901 and haven't looked back since. I should have bought the ET2 a long time ago, now I enjoy the music the way it was supposed be with NO inner groove distortion like regular tonearms have.
