My ultrasonic essential oil diffuser runs on 24v. It makes an annoying mosquito noise when running. Think an ipower would make it less noisy? Lol

Why don't you buy one, do an ABX test, and report back? You can always return it if it doesn't sound up to par. IMO theirs no better value than Ifi. I cannot believe there are still people spending thousands of dollars on exotic power supplies and conditioners. Personally I prefer wall warts...

Makes sense. So I take it the new Ipower X is even closer to the nominal voltage due to tighter regulation? Was the cable upgraded too?

Any owners with a voltmeter handy able to give us a real VDC? Original 12V Ifi was only 12.14V, which seemed a bit anemic compared to the OEM wall warts I upgraded from.

I'm tempted, but think I'll hold off till they're on sale. I'm willing to bet with all the tweaks I've made to my old ipower, it's already way quieter. I've actually taken a couple ipowers apart and modded them extensively... noticed many visible and audible changes/improvements between newer...
