Dear Fosse: Like all other Dynavector tonearms the 507 MK2 is a dynamic balance design but you can use it in static way using , like you say, the counterweight only. IMHO and over my experiences with those tonearms it performs better in a static way but like almost always that is system/ears dependent.
