The Transcendent Sound balanced power supply, has no MOVs in its circuitry. There is lots of capacitance but nothing to really deal w/ a surge. Transients on the power lines where I live has never been a problem, probably too many transformers between me and the generators.
I don't think that short of unplugging all devices that there is any protection against a direct lightning strike.
So in answer to your question, no.
