"Unfortunately, blocking the +5v doesn't get rid of the ground loop."
I think many people are using isolated 5V supplies, to simulate a host side connection, after cutting the power lines.
But unless the data lines are also isolated, the ground loop with the pc, through the usb cable, hasn't been eliminated by using an isolated 5V supply like that.
Perhaps if Amir wanted to do a video lessons on the type of equipment arrangements more or less likely to increase the strength of unwanted humming signals and other EMI, especially as it pertains to how people want to hook the gear up, even if he didn't have explanations for all his findings, at least there is something to talk about. I can understand the hesitancy to declare positive results without lab grade power for his equipment, etc. but I'm betting he'd probably help shed a little bit of light on the dark art of hooking stuff up correctly, for some people anyway.
