Mine hasn't arrived yet, but from reading it seems most describe the NFB-11 as having a neutral bright sound. I understand the Beyerdynamics to be fairly bright uptop , so depending on you taste you my find it a bit on the bright side.

I have no personal experience, just relaying what I have read and how I understand it.

I think the NFB-11 is neutral.

You often here the description of it as "bright" in comparison to the NFB-15, which had a bit warmer sound. This, I think, has propagated the idea that the NFB-11 is bright, which I don't agree with. But just my personal opinion.

We'll that's good to hear.

Mine will be delivered tomorrow or lately Wednesday. I will make some pictures because maybe someone is interested to see all the accesories or how it is shipped. (As far as I know they send only a power cable and a USB one, for me I already bought a 2m TOSLINK one).

 

[OctavianH]

Mine arrived earlier than predicted, in perfect condition. I will try it in the evening because now I have to return to the office.
 

 
It was shipped in a simple box with a power cable and a USB one. 
 
What I do not know is the function of the back button (only I and II written on it). Can anyone tell me what this button does?
 
 

 

[OctavianH]

OK, I found what the switch does:
 
Mute switch :  Push 1 for active the mute design, Push 2 for suspend the mute design.
 
But what is that mute  design?

For DSD pop sound.
 

 2, Because the NFB11 had the hardware mute design , not as our other products had the software mute design, so we addition a switch for select active /suspend  the mute design for  remove the DSD music pop sound. Even always stay on active state ,it still can working fine with PCM and DSD music.

 

[OctavianH]

Ok, last question. This device does not have ON/OFF. Should I stop it always from the power supply switch?

Yes

Just recieved the NFB-11 yesterday. I have to admit I do find it a little bright compared to what I'm used to (Sound Blaster E5 and JDS Labs C5D).
 
I Installed Equalizer APO to add an equalizer to windows and try and EQ to tame it a bit.

 

[OctavianH]

I find it neutral. I try to avoid all kind of equalizers because in my opinion they add noise to the music. So for me only foobar with WASAPI and no equalizer. Indeed, sometimes I prefer a warmer sound, but I am not sure how you can make the nfb11 warmer. Maybe different headphones or another amp on the RCA outputs?

I usually don't like to use EQ unless I have to and avoid software enhancements, but I can't hear any negative affects and lowering the treble makes it easier to listen.
 
Yes, a different AMP might help. I'm considering a few options but can't do it right away so the EQ will have to due till then.
 
Considerations:
 
1. Garag1217 Project Solaris (AMP)
2. Gustard H10 (AMP)
3 Aune X1s (DAC?AMP combo)
4. Sennheiser Orpheus (DAC/AMP/HEADPHONE).... ok just kidding on this one.

I don't know about the option 1+2 Amp but the Aune X1s, don't. From what i remember reading reviews, the X1s is pretty similar to the NFB 11 but the NFB 11 is a little better (Aune X1s use ES9018K2M chip while the NFB 11 use ES9018). If you prefer a warmer sound you should buy the NFB 15 not the NFB 11.

NFB-15 is not available anymore at audio-gd. I asked about it before ordering NFB-11. I am not sure if I will pair it with another amp, but I am curious to see what options I have for warmer sound.
 
What do you think about Creek OBH 21MKII?

Dunno. I never hear about it. My knowledge in DAC/Amp field is very narrow.

 

[OctavianH]

I excluded Beyerdynamic A20 because as far as I know is neutral (so the same as the one on NFB-11)
