Default Zen 9 and 90Hz

Would someone mind explaining to me what running the power feeding a Zen 9, or for that matter any amp, at a highter frequency rate might do?
The reason i ask is that i have a PS Audio 300 power generator that allows me to vary the frequency of the AC.
There may be some sonic advantages, minor admittingly, but still vaguely noticable at least to my ear, at running the power at 90HZ. I have noticed that the amps tend to run a little hotter, is this my imagination?
Any thoughts would be greatly appreciated

Transformers run a little more efficiently with increased frequency,
so you might be seing a little more voltage on the rails for your
trouble. Also, the filtering is a little more effective, so you might
see a bit less noise.

... and perhaps that little less noise is what's translated to slightly deeper bass.

Any potential long term harm to the FETS or is it much of a much ness.

As alwyas grateful for the response
