It's sounding okay out of the headphone jack   but there's something missing, it sounds a little be veiled and trebles seem a bit brittle. The amp isn't very dynamic,  though they give my LCD-2 a lot of juice. Hopefully I'll change my view with burn in and using the balanced output.

 

¿Is there a diference in power between normal jack and balanced output?
 

Yes, give it a week of heavy use. 

Thanks for the heads up. Btw I'm using it   USB > NFB-1.32 DAC <->  ACSS cable <-> NFB-6  ,  so it should be fully balanced mode when I get the XLR cables
 

Yep, that's the best operating mode ;)

That's a nice setup too ^^

At least for now, it seems okay with head phones, but it sounds real good as an pre-amplifier, using it to feed Edifier T1900III, packs a lot of punch

The difference between the sound of this amp single ended vs. balanced XLR is like night and day.  Unbalanced the sound is exactly as you describe veiled and with brittle treble.  Balanced and with burn in, it's incredibly detailed and uncolored.

Thanks for the info, I was actually starting to "not" like it  because in some frequency ranges there's a lot of detail missing and it's harsh.
 

Here is a new member of the NFB-6 club :) To answer my own question: NFB-6 sounds significantly more neutral than C-2.1 in the same setup. C-2.1 tends to be more on the warm side. NFB-6 is currently somewhat grainy and imaging is not spectacular. But this is out of the box and using SE. Next week I am planning to go balanced with my D2000 and will post more impressions. Let the burn-in rollercoaster start! 

A question for NFB-6 owners using balanced headphone connection: I have reterminated my headphones with Neutrik NC4MXX but it does not lock to the connector on the amp (it can be unplugged without pushing the lever). Anyone having similar situation? I have no issues with the playback or SQ, but it seems strange it does not lock, because both the headphone and amp connector are Neutrik...

The NC4MXX might not lock due to it's different locking type- the ones I use have a "window" (I use NC4MX with my balanced AGD amps)

Yes, you are right: NC4MX has a window trough the metal barrel and NC4MXX has a pit inside the barrel. No big deal, but I was scratching my head in confusion 

I have read somewhere that NC4MXX is of the higher quality than NC4MX, but this might be completely wrong...

Maybe that is audiophoolery- it transmits the signal just as well I would bet.

I'm going to use the pre-amp with a M-Audio Studio Monitors that have a XLR 20Ohm input...     will the pre-amp work well with those cans?
 

Been a while....life has gotten in the way the last 4 months.  

Just wanted to post a quick update.  The NFB-6 is wonderful sounding as a preamplifier.  After several hundred hours of usage, I am hearing things that I haven't heard with my other preamps, and it really delivers the detail in a non-clinical fashion - the music seems to flow freely, and I always find my toes tapping.  I haven't had much of an opportunity to listen to the headphone stage yet, but a quick listen single-ended was reasonably good sounding.  I don't currently have a set of balanced cans, but I will be starting the search soon.  

King-wa did an excellent job on this preamp.  Even if there was no headphone stage, this preamp would be worth way more than it's asking price.  I have a $3K preamp here that has lost it's position as my main preamp.  Well done.....bravo!
