Lewm et al, theET2 definitely goes out of level in my experience on Oracles ( the worst ), Linn's etc.
I don't think you can just slap an ET2 on an Oracle and expect it to work well. I bought my Delphi with the ET2 arm already optimized for it which included the counterweight under the chassis (on the front left "arm" between the bearing and the suspension pillar) and a spring adjustment. When my tonearm traverses the record, there is not enough "sagging" of the chassis to causes the tonearm to accelerate. The cartridge leads have more influence, which is virtually nothing, than sagging. I've optimized their placement to have the least effect on tonearm movement. I often wonder how the Kuzma Air Line's thick air tube influences arm movement.
Maybe the performance of my table has to do with the fact that I adjust my suspension while the cartridge is at the middle of an LP. I can see how leveling the platter while the tonearm is at the lead in groove will cause arm acceleration as the arm traverses the LP.
