Mapman,
Agree!!
Just thinking aloud, since no one has come forward with their experience.
Another thing that is possible- considering phase is manipulated, there is a fixed frequency window - band width limited (which may be the case in PWM as well). However as my understading goes, there might be an error correction factor needed, may not be the tradional negative feedback, but maybe along the phase wave. Negative feedback if institued properly is generally a nonissue. Probably that's why it's called SOA, where all parameters are optimized.
