Sorry, but I've never had any imbalance issues with AT or other cartridges.Although I am not qualified to have an opinion, my personal experience leads me to think that it is maybe because there are more of us than we like to think with unbalanced hearing.
Only with Rega Exact (at least with 3/4 of them).
No issues at all with Elys2, Bias, Ania and Apheta 1.
