Yes!
I, and many of my Head-fi meet friends have noticed how good my DT880-600's sound with this DAC. Very 'acoustic' with a slight warmth.

 
This Dac/Amp impressed me with many of the Beyerdynamic headphones. I've listened to DT880's 600ohm, T1's, as well as these DT 770 250ohm headphones and all sounded nice with this amp. So far though the DT 770 250ohm being my favorite match.

Hey guys. Just got a NFB-12 and was wondering if anyone had issues setting the NFB-12 to 24bit via Windows? It shows it as an option but when I set it and hit playback I get an error message saying that the test track couldn't be played.

Setup is : laptop (Windows 8.1 Pro) >> 7 port usb hub (self-powered) >> NFB-12 >> DT880/600ohm.

I haven't had the chance to pop the top off to check the filter settings yet but reading the manual on the Audio-GD site, filters seem to effect only freq range. Thanks.

You might have more luck asking here as it basically covers all the Audio_gd's: http://www.head-fi.org/t/638252/audio-gd-usb-32-firmware-drivers-and-feedback-thread/180#post_10229578

I think that the NFB-12 uses a Tenor usb chip, and not the usb-32

Correct.

Thanks for the suggestion, but I solved it. Turns out that using a different usb port fixed it. I don't know if I need to keep that slot empty or what. I'll continue to test it out.

My zero DAC's power button stopped working two weeks ago and it cannot be switched off anymore.

many thanks.

I would go with the NFB-5.2, which is a better and more flexible unit from the rest
If you use the usb input, the NFB-12 is clearly below of all other options

 

[Matrixnobu]

I wouldn't discount the nfb-12 though. It's a decent amp/dac.

 

[tim3320070]

More than decent, it's excellent

 

[Matrixnobu]

I agree. I've had mine for about three years now. And I never felt like I ever needed to make a change. And its well made. I've had mine turned on day and night for all this time and no problems whatsoever.

It is excellent, and an amazing match for certain headphones. (DT880...)

Yep - this ^^
 
Also the HD600 shines with it.

Anyone want to sell me their NFB 12? I already own the 10.33 and its great.

When you guys use the line out, regardless of variable or fixed level, do you guys use low or high gain?

I seem to get better sound with it on high gain while using line out to my c2 class a

 

[Brooko]

High gain on variable when using my passive monitors
 
Low gain on fixed when going to the Little Dot.  The LD has plenty of power anyway - so makes no sense going high gain and raising the noise floor.
