They all look the same, is the only difference in the treble?

Why not just turn it off when you're not using it...? It's a flick of a switch. I doubt you listened to it 48 hours straight with no breaks.
No. Your headphones are not on your head 48 hours straight. If that's the case, you have bigger problems than an overheating headphone amp.
So you never leave your home? And you never turn off your music? How do you get food? When is the last time you saw the sun?
The complaints about the heat of the NFB-12 seem to be legitimate. I left mine on for about 2 days (listening to music while I'm sleeping, listening to it while I'm awake), and suddenly it powered off. Touching the top of the unit was nuclear, too hot to touch.
I think it has a bad power supply, nothing looks burnt or blown inside. It's safe to say that it was killed by heat. Room temp at death was a fairly chilly 8'c / 46'f as well..
That's interesting. And it still is not working, even after cool down?
By powered off, you mean that nothing works anymore? The LED doesn't light up, it's not recognized as a DAC trough USB, no audio out.... Since it has a different power supply for each of these features, if nothing works you probably burned the transformer itself.
This thing was not designed to pass safety and performances tests like the ones performed by UL. It's not designed to be used non-stop for days. I'm not really surprised it died.
