I agree with Frogman. The loading values for an MC are listener and system dependant, however, it has been my experience, especially with the Benz LP and LPS, that wide open at 47K sounded best. Loading at 1000 seemed best for me while the MC was breaking in, however, I experimented with other load values and decided that wide open (47K) sounded the best.
