@dsper I read through the comments before deciding to comment my self and it seems you tried what I was going to suggest and that was dropping the rear of the tonearm to reduce sibalance and improve bass response. As well as dropping the capacitance on your phono stage.
The other question I had was when KAB wired your tonearm, did you have them install their arm tube damper?
In addition to damping it also adds a little mass to the arm. I did my MKII arm years ago with their litz wiring and the damping tube.
It made an audible difference
