    Hello, would you at least say that perhaps the DAC of the NFB 11/15 is about as good as the NFB 28/29? 
     
    IN what ways would you say make them sound different; and are these differences tied in mostly just to the DAC or the amp sections? I'm mainly planning to get the NFB 11 to use as a DAC for a medium spec. tube amp and would just be using the built in amp sometimes, so am wondering if the DAC would power that well enough?

    I think mostly in the amp department. Some DAC improvements too.
    The units are bigger, with better PSU, etc.

    It is easier to hear the differences of the amp sections.
    Expect clearer and smoother sound and a little better resolution from the more expensive units.
    This does not mean that NFB-11/15 are bad, but it will be easy to hear better gear.

    Can you hear hissing when you put this on high gain mode and turn the volume knob all the way up while no music is playing ?

    I was able to hear hiss on NFB-15 which has the same amp section on low and high gain when I pass 12 o'clock.

    I put my G109-S on high gain and turned the volume all the way up, Dead silent. I was contemplating to buy the NFB-11 but what you said put me off. I guess I should look else where.
     
  7. Jakkal
    You have a great amp, why you consider NFB-11? For the dac?
     
  8. Sam21
    I am building a second setup...

    Take a look at Project Polaris and you can paired with cheap dac like HifiMeDIY Saber.

    Its silent at 12 o'clock at either gain setting. It's not until you get to about just before 3 o'clock (about 75% volume) that you can start to hear a slight noise. It's completely normal and no where close to regular listening levels, where the background is silent. You are comparing a dedicated amp in the G109S which is a very good amp, to a entry level amp/DAC combo in the NFB-11/15 which is un-equalled in terms of price:performance.

    I bought my NFB-11 in Oct. 2014. After this long time period of using, I found that this console satisfied me most in its DAC part, I used NFB-11 as a dac then connected to my Musical Fidelity M3i amp to drive my Sonus Faber Venere 1.5 bookshelf speakers. The soundstage is really amazing, every detail can be heard and seperated perfectly than I have heard on HD800 DT990 Q701 and Sr325e when driven by NFB-11 itself.

    All the comments about how better it is with an amp connected to NFB-11 makes me want to invest in a separate amp...only if I had the funds.
     
  13. Zaiki
    Yes that's the point.

    Just got my NFB-11 with TCXO upgrade and I'm having some strange behavior. 
     
    I use Windows 10 and Mac OS X with optical via my onboard sound and USB via a USB 2.0 port. 
     
    In both OSes, when I use the device over USB it seems to shut off or go to sleep every time there is no sound. This causes a half second delay in hearing new sound, which basically means I can't use it as my external sound card because no notification sounds will ever be heard. Is there some way to get it not to go to sleep? 
     
    Also, I had significant popping when I tried to play a 16-bit / 44.1 file while in DAD 32-bit / 384 mode. Also YouTube videos basically had no sound when the OS was set in this mode in Windows 10. In Mac OS X it seems to work sometimes. I set the bit rate in the Audio MIDI Setup utility to the 32-bit 384 and it either works, or I get significant popping. I'm guessing the USB can't timing sync with the computer? 
     
    Anyway, I mostly use Mac OS X (Hackintosh setup) but on both OSes I'd love to be able to shut off the onboard audio completely and just use the NFB-11 as my USB sound device in both OSes for all system sound.
     
    On the plus side, I don't mind the 24-bit/96khz optical, which works flawlessly and the sound is incredible to be sure. 
     
    Here's my part list: http://pcpartpicker.com/p/JcQkP6
     
    Motherboard is an Asus Z97 Sabertooth Mark 1 with the latest BIOS.

    Do we know for sure which Sabre ES9018 chip is in the NFB-11? Apparently there is more than one: http://www.esstech.com/?p=products_DAC
