Focusedfx, Does this sibilance seem to be equally strong through both channels? If it appears more in one channel, I would attack the anti-skate issue. I had a WT Classic 'arm for a couple of years and found it to be difficult to work with for anti-skate. I ended up with too much anti-skate because the other parameters were right in that setting.
The lack of a precisely determined pivot point, a suspended, partially floating paddle in damping fluid probably all contribute to small changes in geometry during play. It's a tricky 'arm, although a very satisfying one when married to the right cartridge, etc.
Could cartridge compliance vs. effective 'arm mass play a greater role in the inner grooves because of the viscous fluid being "moved" more by the rotation of the 'arm? Maybe a better cartridge compliance/effective mass match would help. Last I spoke to WT, they really liked the Sumiko cart's.
(I used the Dynavector 10X4 and Benz Glider with the WT Classic with good results. No inner groove sibilance. But...that was some time ago.)
