yea, if that was an issues it's guaranteed that people would have been complaining about it already.
 

Gain setting loosens

If you look at the USB input, you can see that it is actually separate from the mainboard and connected to the USB receiver through 4 wires. I assume one of these wires is the 5V from the USB. Rather than using the crude electrical tape mod, maybe you can disconnect the USB 5V from this end? I'm not certain and I don't have the knowledge of how to figure this out.. just throwing it out there for others who may have more knowledge on how to accomplish this.

A user has written his feedback on the nfb1.32 product page about the usb32 being powered internally, not sure if this is what you meant.

When I switch 1.32 on again, the gain setting loses track, originally Low, bounces back to the default High.:what: If I notice it, I switch back. After some switch off and on, it will slip to Low.

Anybody also sees this happen?

my 2cents!

The logic gets haywire could be due to the internal jumpers or connectors, related to the gain switch, having intermitten contact.

Try open up the top cover, plug out and in the connectors or jumpers a couple of times, or wiggle them a little if they are glued.

Check on the male pins if there are any residues on them, and the female molex connectors if any wires are breaking off where possible.

This is a something similar that happened to me, when i initially got one of my stuffs. There are some sorts of laquer-like residue that tainted few of the pins. when the amp gets warmed up, it sort of melted the coat, and i got no issues then.  

I understand that it is powered internally, but it is still getting dirty power from the +5V line on the USB cable. There have been mods of people covering up that line with electrical tape so it doesn't get to the NFB-1.32, but I was wondering if a more elegant mod could be performed internally using those exposed wires.
