Channel Balance on Dynavector XV1-S

Hoping I can get some advice. I have a XV1s on a Basis Vector 4 arm. I just borrowed a Fozgometer and I'm getting very different reading from the 2 channels.
-I downloaded and tested the Foz and it seems to be calibrated correctly.The Vector 4 azimuth adjustment is extremely precise and refined, like all things Basis, so I'm pretty sure that the arm is good and the Azimuth is correct.
-No matter how much I changed the azimuth, the balance/imbalance stayed the same (same levels as well), about a 5 reading for L and about 7-7.5 R with the tonearm cables running directly into the Foz and 14.5L and 19R with the Foz plugged into my ARC Ref 5 SE Phono Preamp. By deduction it would seem that it's either the cart or a tube(s) in the phono pre. Any insight or advice will be really appreciated.

This thread may be relevant. The link opens at the post which describes the conclusion in that particular situation.

Since the signal issue changes evenly when I change the tonearm wires on the cart pins from L to R, I think that this rules out the Foz and the test LP as variables.
Moryoga, note in the thread I linked to earlier that the Foz was found to be at fault EVEN THOUGH the imbalance it indicated followed a channel swap at the cartridge pins. I certainly have no idea how that could be, but note also that the OP in that thread reported several others as indicating to him that they had the exact same experience. With one of them indicating that his Foz worked fine with two of his turntables but exhibited the problem with another turntable.

And it appears that in most or all of those cases it was the right channel which measured higher (when the cartridge connections were not being swapped).
This process stated because there was an obvious sound difference between the 2 channels.
That was also the case in the thread I linked to. As you may have already read, it turned out that an unrelated second problem was simultaneously present, which was causing the audible imbalance.
