PS Audio DirectStream Power Plant 12

According to this post on PS Audio's forum, if I understood correctly, MultiWave adds a variable amount of odd-harmonic distortion into the sine wave output.  That would tend to push it somewhat towards a square wave, the idea presumably being that the regenerator can then deliver more net power into the downstream equipment (e.g. to charge linear PSU capacitors) as something close to the peak voltage is maintained for a higher proportion of each cycle.
