Light Harmonic Lightspeed USB Cable Sweepstakes

Register to win a Light Harmonic Lightspeed USB Cable (MSRP $1399.00) we are giving away.

According to the company:

While designing the highest speed USB DAC on the market (Da Vinci DAC), Larry found that the USB cable was one of the weakest links in many computer-based front-ends. By isolating the USB power, re-clocking the signal, and buffering it with our patent-pending 3 layer buffer, Larry minimized the cable's effect. Even so, bit-perfection of the digital signal and original precise timing was often lost by the USB cable. How to fix it? Engineer a better cable.

We tested dozens of "high-end" USB cables and found that many can't achieve the 480Mbps bandwidth requirement of the USB 2.0 high speed standard! Even worse, signal integrity is often damaged by the noise in the power leg of the cable.

Lightspeed USB uses a unique topology, which we call Ultra-high Speed Differential Pair (or USDP). USDP gives Lightspeed 20 times the bandwidth of USB 2.0 high speed, which ensures optimal signal clocking. In fact, Lightspeed's astounding 10 Gigabits per second bandwidth is twice as fast as USB 3.0! Additionally, its 2-in-1 architecture physically separates the signal leg from the five volt power leg, preventing source-generated noise from disturbing the digital signal. The result: a bit-perfect USB cable.

I will get my wife to let me get a DSD/DAC if you give me - er, her - this cable. Then we can work on some Ayon or Lamm or AR equipment to replace the old Marantz.

I'm intrigued about how a cable increases a speed I thought was set by the port but hey, if it works, I'd love to give it a shot.

eeifb's picture

I could really use it.

doublewooddc's picture

I should get bonus credit for the clever, audophile-esque, somewhat lame play on words.  =-)


Good luck to everyone else!



P.S. Enjoying my recently aquired Schiit Asgard 2 in my work office.

Okay, this goes for more than my TEAC UD-501, but I believe in spending more on cables than the electronics, especially if I can win these.
