Would you plug your sensitive audio equipment into a power outlet shared with a refrigerator? The current draw of the refrigerator, when it comes on, will spike the power and cause audible pops in your speakers.

When you plug your USB DAC and other USB audio devices into your computer you're basically sharing an outlet with a power spiking device. There's a power line inside every USB cable that carries all the noise and grunge made by the computer directly into your DAC. This limits the performance of your DAC.

USB Disruptor corrects this problem. You have to hear it to believe it.
