Problem: Power. Solution: ?

Euphoria and beyond! Now yer talkin'!!

You probably have access to 460 three phase power. I'd get a BIG isolation transformer, 460V, three phase...

I remember reading about mov's in an expert article in Byte magazine years ago. IIRC, there are differences in quality, but they all fail after a certain amount of stress, leaving your equipment uprotected. At that time, anyway, the technology allowed the mov to fail with no visible evidence that it had done so. The writer recommended a different approach to surge protection. I believe he preferred transformers.

"Euphoria and beyond"-- A little over the top?? Reminds me of the line from "White Men Can't Jump": "I love you infinity plus infinity"

IMHO: PS Audio P500 is the best way to go, if you can afford it. It gives a steady 60hz sine wave, isolation, surge protection and doesn't limit current like lots of other filters. You can't get better power than a pure 60hz sine wave. I use two P500's. Together they cost more than my integrated amp, but they're worth it. I could have purchased one P1000, but two P500's allow me more outlets, better isolation, better cooling, and more flexibility. They make a HUGE improvement in sound quality. BTW: I have no affiliation with PS Audio, and nothing to sell you.
Best wishes,
