USB optical cable : stunning IF powered & implemented correctly

[fds]

If the computer is a laptop running on battery, I do not see how it will pollute the mains. Also I am not sure how much of the noise will travel down the USB cord, in particular, if this is made of fiber. What will remain though is some computer-caused jitter that will travel down the USB line towards the DAC. However, now with a good well-powered reclocker such as an IsoRegen on a good LPSU or a Phoenix, that jitter will be reduced significantly. Thus, I think @tgb has a very promising approach there ... In fact, I do find the term "new paradigm" quite suitable.
