If you go to Loricraft's website and read their explanation of the benefits of their motor controller, keeping the 301 motor operating at 50 Hz keeps the motor running at optimum efficiency.
The benefit is the motor is running smoother and quieter at 50 Hz vs 60 HZ, with less noise and vibration. Their tests show added noise when operating at 60 HZ.
Once again every attempt is being made to elevate the 301s ability to provide a quiet stable platform so that the tonearm/cartridge can retrieve as much micro detail as possible.
