The reason for this is that the XSD-15, which has an SME-type bayonet fitting, comes with an especially long shaft, which makes it protrude much further from the end of the Jelco than a normal detachable headshell, thus I suspect skewing correct alignment by quite a significant margin. Therefore, as there is no alignment adjustment possible on the headshell, and as the Jelco arm itself cannot be moved in any way, I'm forced to look at other options...
What I thought could solve the issue is to go for an EMT arm, that would thus allow me to use the matching TSD-15 cartridge, which crucially has a very short and stubby shaft, shorter in fact than even that on a normal detachable headshell (in fact, it almost mates directly with the arm), so I suspect that this would likely allow for correct alignment, but of course it is by no means guaranteed - the only way I'll know for sure is to try it and see!
