This decrapifier isn't as "snake oily" as it seems, as far as I understand its purpose. It's meant for usb powered dacs, where if the power coming out of the usb port isnt perfect, clean, and constant, it can and will cause some serious sound issues, because you would essentially not be getting correct power to make the dac work. And I'm sure on some computers depending on where the port is located or if anything else is on the internal hub other than the dac, then something like this device can come in handy by simply providing a constant power supply through the usb cable for the dac, and keeping the signal alone from the internals of the computer, so its as uninterrupted as possible. If you have a powered dac, that just has a usb input option, like the bifrost for example, then this device is basically useless. unless you have some serious usb port issues/noisey internals in your computer or something. but this yould make a good alternative over a powered usb hub for a usb powered dac.
