If you have the tracking and other issues you related below, perhaps it is not the XV-1s that is deficient. I personally have never had any of these issues you describe on all your tables.
BTW, I have never heard the XV-1 sound particularly good when used with SUT's. Wth dyna carts I agree with Raul and active phono stages are a lot better. That is why dyna made an active head amp and not a SUT- to get the best out of their carts.
To be more precise, I've had Avid Volvere and Oracle Delphi V and VI tables, 2 SME Vs, one Graham Phantom, and multiple cartridges including Benz Ruby, Zyx UNIverse, Dynavector XV-1s and Ortofon MC A90. In every case I have had EXACTLY the same issues you are describing - with the added caveat that some of the combos gave me tracking issues in the right channel. With my current set-up (Delphi VI, Phantom and A90) I seem to be getting the best overall tracking performance but only with more than max antiskating and the DIN connector rotated all the way counterclockwise. All in all, skipping in the lead-in groove was worst with the XV-1s (the issue you're having) and tracking was worst with the UNIverse - the issue always appearing to be related to excessive skating force causing skipping ahead or mistracking.
