I did a blind test with someone who bought it, along with the Sabre U2 DAC: I prefer the sound without isolator than with it. With the isolator it seems to me that sound lacks power, especially with the low frequencies. This is subjective but done in blind test with consistent results. Maybe the isolator limits the current available to the DAC? (thus the lack of power in sound) Or that isolator could be defective. Could someone try this blind test with someone else who plug and unplug the isolator between the DAC and the PC ?

I had noise issues coming from my desktop PC USB ports. All of them. I was happy to find that my audio interface needed less than 200mA (it needs 150mA) so I decided to try this USB isolator. It works marvellously! I hear absolutely no noise. Even with my unplugged laptop I would get some noise but with this little device my audio is as crisp as can be with any computer I've tried it with. I'm so glad it solved my issues without shelling out legit cheddar on an industrial isolator. Big up!

The USB isolator works well filtering out the noise from my desktop USB port, connected to my Dr. DAC2 DX. I use Dr. DAC2 DX for Op-Amp rolling, and has been using it as headphone amp, connected to Yulong DA8. Yulong DA8 analog out connected to Dr. DAC2 DX analog in. Both DACs are connected to USB ports of my desktop PC. I keep getting high frequency noise on both of Yulong DA8 & Dr. DAC2 DX headphone output. I tried with AC power filter, didn't solve the problem. I found out that the noise came from USB connection to Dr. DAC2 DX. When I disconnected the USB cable, the noise disappear. So I tried this USB isolator from Hifimediy, put it in between desktop PC to Dr. DAC2 DX USB connection, and the noise disappear :D USB isolator doesn't work for Yulong DA8. Yulong DA8 was not recognized by Windows when I used the USB isolator. But it works perfectly for Dr. DAC2 DX. Thank you Hifimediy!
