Aside from the Power Inspired units, do these exist? Is there another name for something that does AC->DC->AC conversion when they're not in the context of audio?
I've recently moved into a house which has various electrical quirks (don't worry, electricians have been called as well).
One of the quirks is that the transformers in two of the amps buzz quite audibly, and there's a hum on the speakers. So too does my sub make an ear-to-a-seashell sort of noise that it never made in the last place. I confirmed the theory that it's due to questionable mains supply by picking up a small online UPS - no such problems when plugged in through that.
Whilst an electrician may be able to diagnose and address any issues with the mains supply, the mains still comes into the house quite hot, and this in itself can cause the transformer buzz, so it got me looking at mains regenerators.
These seem to come in two flavours - audiophile and not. There are plenty of AC regenerator units out there from PS Audio and their kin whose descriptions and specifications are laden with audiophile tropes and price tags to match and they hold no interest to me - I don't want to start a debate about their benefits or not, just to say that a mains supply that's not garbage from a relatively los cost UPS resolved my issue, so I have no need for anything theoretically better than that. A much larger UPS could form a permanent solution, the battery component adds weight, maintenance, heat, noise and just isn't needed.
The Power Inspired units seems to tick all the boxes, though availability isn't great - are there any alternatives out there? In a commercial/industrial context do these have a different name that my google-fu hasn't come across? As surely "AC regeneration" is a valid need for all sorts of areas other than audio, but the search term "regenerator" only picks up audio products.
