It sure looks off center to me. I would send it to SoundSmith for the $250 level repair.
I have had both SS (two different times) and Axel of Germany repair cartridges both of them with excellent results.
I recommend you send to both of them a couple clear pics (15 and 16 ? ) so they can give you an estimate by email.
Axel communicates in English very well through email.
You have the SS info in the previous post.
