Worked perfectly to remove a super high pitched whine from my PC's dirty USB ports. The horrible noise was louder than the music before.
Not sure if it was EMI or a ground loop, but it's all gone now! I'm impressed and surprised, as this computer/room has proven to be a very dirty RF/EMI environment! Just tested a bunch of the noisiest USB ports and so far they've all come clean with this little guy. Even the noisy LED-backlit gaming keyboard output comes clean, as does a USB3 hub with a bunch of devices on it.
My setup is Desktop PC to monitor to an Audioengine D3 to a DarkVoice 336SE tube amp. The music comes through clean and silent now.
Also works fine with my XDuoo XD-05 DAC/Amp, but that wasn't noisy to begin with as it's battery powered and doesn't drink the dirty USB juice or connect to ground power-wise (it uses a cell phone style wall wart to charge the battery on a separate circuit).
The little black box labeled 'mornsun' does appear to get a little warm, and yeah that blue LED is way too bright, but otherwise this thing is great. I can always apply some black electrical tape if I need to block the light.
