FYI to future buyers, the DAC may not install on your computer...
I got this a while back and I tried redownloading the driver from their site but my computer (win8) wont recognize that the driver is connected.
"Setup requires that the device is plugged in. Please connect the device you want to install and make sure it is turned on. If you're device is currently connected, please unplug and replug it."
I tried everything...
