Yeah, implementation is more important. I have a wallwart powered usb hub that it would atttach to, which also happens to be powered by my furman pl-8. So any power the bridge would be getting would come from that, although i heard about something called a USB Isolator (which is basically the same thing) that probably uses this idea better than a typical powered hub. Might have to look into that some more. I would definitely like to know if daisy chaining transports would be beneficial. That would be quite interesting to find out!
I've got a USB isolator coming for the Bravo, not sure if I will really need it on a Mac, but I boot into Windows also:
Also it may not be necessary for the Bridge either from what I understand.
