begineringHmm... I think this is also interesting: https://vimeo.com/155057552. Check between 7:20-8:30 where he talked about PSU noise. Above all, I think a high quality psu always provides positive reward. The problem here can be 1) noisy usb power (yes but usb power isn't used for many non-usb-powered devices; 2) ground loop (this is BIG and universal if you connects multiple devices together). It is actually better if you just isolate your usb ports regardless of the psu you use. Products like ifi ipurifiers works really really well.

begineringI've been thinking of getting this to improve my DX3 Pro audio chain, but after reading the Audio Science Review take on it, I'm not convinced that spending $100 on this is worth it. I'd rather invest $40 in Mogami 4 core / Neutrik RCA interconnects between my DX3 and Sony integrated stereo amp which has been on my wish list for a while. It could make sense if there are electrical issues in certain areas, but I can't hear or detect anything where I am. Also, realistically speaking, I can see where ppl spend $100,000 - $1,000,000 on a hifi system wanting to have power conditioners (which also serve as surge and lighting protectors) to push the envelope, but with the average Joe's audio system I don't think there's much of a case for a dedicated power supply like this that costs half as much as the DACs its powering. Maybe if it was a $30 or $40 unit then it could be in contention, but $100 is a lot. Maybe if someone gifted it to me it would be cool? But on the other hand I can buy 5 nice vinyl records for the same money, and I'll get a lot more enjoyment out of those than having a big power box sitting behind my table. I'm sure others have their own versions of trade offs that would be better than buying this.
