I think it's principally a matter of the easily-switchable digital filters through the front panel display. Don't think there are any other major differences.
i agree the 3.1 sounds better warm (too splashy cold - i guess this is because of the lack of feedback and it being adjusted to run correctly at the usual operating temp).
but i just wanted to drop a post here to say thanks in public to the folks at audio-gd. i received my nfb 3.1 in early november last year (2011) and it was fine until a few weeks ago, when i moved it to a different room (to do some listening tests) and found that, when switching back on, the screen was blank and the buttons no longer worked. eek. curiously, it was still converting - the optical input was being sent to the audio output. since i live a long way from hong-kong, and had already had a bad experience with dhl charging extra for delivery (not audio-gd's fault) i wasn't too keen on sending it back, but after a few emails and me poking around with a multimeter, kingwa suggested that only the control board had failed (the clock, apparently) and offered to post me a new one. that arrived today, i replaced it, and everything is back to normal (at no cost to me). sweet! so thanks to some trust and cooperation on audio-gd's part i only missed a couple of weeks of listening.
Wow thats great to know as i have alot of A-GD Gear. No problems with anything yet. Awesome that Audio-GD for provides such top notch products and service!
1) Does anyone know how a Squeezebox Touch DAC compares to a NFB-3.1? (I know of one person on the Head-Fi product review page who commented that in a blindfold test he was unable to discern a difference)
2) How about a Headroom Micro DAC compared to a NFB-3.1?
3) There were a few posts some pages back in this thread that the NFB-3.1 uses inferior components to the NFB-3 but that the overall sound is not impacted. Has this been confirmed?
I'm trying to decide whether to finally upgrade my Headroom Micro DAC now that I've got a Squeezebox Touch. The Micro DAC seems to have the edge on the Touch internal DAC. I'm wondering whether the Audio-GD NFB-3.1 would be better still? Does anyone have any experience with comparing these various components?
So my next step is to get the C-2.2 and one of the NFB DACs. I hear the 2.1 is better than the 3.1, but is it worth the price difference? The 3.1 is $165 cheaper... at least right now. How different are they in sound? Also, I assume the ACSS cords are sold seperately.
just sold my NFB3 and C2.2 Combo (With ACSS) so i could buy a NFB10SE. was very sad to see it go as i loved the combo, had amazing synergy with my denons.... but im gonna pick up some LCD2's soon and i want to try balanced. Im hoping the NFB10SE's Dac implementation is as good as my NFB3. If im not happy with the NFB10SE i dont know what ill do next... maybe pheonix? ughh my wallet hates me already

iirc, according to kingwa the only sonic difference is NFB2 have blacker background. whether it worth 165 more or not he leave it to the consumer to decide.
