As I have always understood it the difference between high and low output MCs was in the number of windings in the coil, the high having more. The rest of the cartridge is the same so the arm isn't the component to determine your choice, it is the phono stage. If the COMPLIANCE of the cartridge is different then it makes a difference to the arm but here I think it is the OUTPUT which is different. I am judging not on the Dynavector but on the other High and Low output MCs I have sold, I have not heard anything to indicate that the Dynavectors are different, does the literature show a different compliance?
