If you use USB for audio and if its 5V line and ground connection connect in any way to your DAC (even if your DAC later discards them and reproduces its own power for conversion), you need the USB Firewall Key. Otherwise you may as well consider your outboard DAC a mere extension of your noisy computer. You will have nice office type sound. 


For audiophile type sound quality, you should use up to three USB Firewall Keys in series. At a later date, we will announce a new supplemental USB product which will bring about an even better level of performance using four USB Firewall Keys connected in a special way. This 'special way' will require an additional plug device in order to make the connection. More on this later. Right now, suffice it to say that anywhere from one to three USB Firewall Keys will bring your USB connection much closer to the ideal, where the DAC receives only information, but no noise, from your computer.
