Tried getting some pics of the cartridge and issue.

Pics of the table in question, cartridge stylus and the tail dragging Dynavector headshell.

Greetings

With that arm at rest, it seems like the VTA needs to be improved, also judging this wrt the height of the platter. Im sure that ive seen a very similar arm on a CEC deck, and another deck that i had in last year. There should be a tiny screw on the arm pillar/collar that will allow for the height increase/vta which should then give the clearance needed at the back of the headshell. That cantilever probably has good compliance, which would accentuate the problem if the back of the shell is just clearing the LP at times.  Fix the vta..its easy to do, and get slighty longer screws. Thats a decent, solid, fuss-free j-arm and performs well.

Good luck  :)

A bit more thought on this after looking at the pic again, you could compare the height(from the plinth surface) of the vertical pivot points of both arms. It looks like the arm on the right of the pic is set at a higher pivot height than the arm on the back left.. A closer look at the arm on the left, the pivot point referenced with the arm tube passing through it shows that the arm is slanted backwards. It could be the height of the arm rest thats misleading/incorrect, but if that is the case and if there isnt a VTA adjustment needed, then back of the headshell shouldnt be touching the LP. The other thing here is that shimming the cart to get the clearance needed at the back of the headshell may solve that problem, but the stylus rake angle will most likely be off. Order of set up should be VTA, then tracking force, then tangency alignment and then azimuth, following this with all the checks again, and then listening to the VTA setting. If the sound is hard/bright without deep bass and highs edgy, lacking midrange and transient attacks too sharp.. then the VTA is too high. Raise the VTA if sound is dull/damped with rolled off highs ,muddy lows lacking definition and dull transient attacks. Any VTA adjustment made at this point will need all the setup points/steps done again.
