Hi Mr. Mike. The DL-103 is a high-performance moving coil cartridge, with an output voltage of 0.3 mV. Since this is low relative to a MM type cartridge, the use of a MC step-up transformer, or a MC head amplifier is recommended. I'm not familiar with the NP-30, but if its a step-up transformer designed for moving coil cartridges, it should be OK.
