Thanks for the replies.
I auditioned the Walker Audio Motor Controller, listening with and without it in the system. It provided a clearly audible improvement, with tighter base, more cleanly detailed midrange, and a softer and less etched treble.
I did not compare the sound of the Walker Audio unit to the NAS Wave mechanic. The Walker Audio unit is subtantially more overbuilt (built like a tank, for life), allows switching between 33 and 45, and allows you to choose phase (all of these functions are missing from the NAS Wave Mechanic). The WA unit is not that much more money, so I now have my TT plugged into one.
I am very happy with the improvement in the sound of my system.
