Light Harmonic LightSpeed 10G USB Cable

The founder of Light Harmonic, Larry Ho, who helped develop USB 2.0, discovered that the USB cable was one of the weakest links on most computer front-ends. Now, more widely known, there were implications of having the power and the signal on the same cable. Therefore, he decided to split the cable into two separate wires - power and signal as well as re-clocking the signal and adding more buffering. This helps prevent source generated noise and maintain the 5v power separate from the audio signal.

I purchased this about a year ago and I've used it sparingly. I did notice a significant difference in how much quieter this cable is than your typical USB cable. It definitely changed my opinion on whether the cable matters or not. I also purchased Audioquest Jitterbugs which also seemed to reduce the noise from my PC even further. I give this a very high recommendation, and am only selling because I'm going to upgrade to a newer model. I never even used the plastic pieces to separate the cables.

20x faster than USB 2.0 and 2x faster than USB 3.0.
