I took a quick look at the industrial stabilizers (Purepower and alike look quite suspicious to me given that they carry AC/DC and DC/AC converters
and claim 2kW or whatever with a very slim and compact case...). They all look like a small fridge, OK, I'd expect that if it is to carry a linear supply inside.
To my surprise stabilization principle is very simple and funny and probably dates back to the early 20th century: a servo motor
controlling an autoformwer and a buck-boost transformer. Very simple!

Of course this is only a stabilizer: even with fast and precise modern motors,
it'll only eliminate the low freq. variations, and will do nothing
to the shape of the AC. But still it can be a basis of a more sophisticated
conditioner (as I understand one of the the problems is to make the RF filtering sound-invisible)
