I'm thinking of trying one of these.  Can anyone give any feedback on the sonic quality that they might have gained from using one of these? 

Any feedback is welcome.

Do they have a "UL" sticker?
One of the reasons for using wall-warts is power line safety.

I highly doubt it.  Heck, I don't know of any "hi end" audio equipment that does.

It's commensurate with the price. It's basically a split bobbin transformer (which is good) but generic LT regulators and Nichicon capacitors. So yes, an improvement from stock but nothing like a good shunt regulator such as those from Paul Hynes.

YMMV,
