What's improved  in the NFB-10ES3 from the NFB-10ES?
1,  NFB-10ES2 : Built in USB-32 ,support up to 32bit 384K asynchronous transfer model , ultra low jitter re-clock ability can cooperate well with ES9018 without sound  drop off .
     NFB-10ES :  Applied the TE7022 support up to 24bit 96K adaptive transfer model .
2,  NFB-10ES2 :  Built in 80 steps relays based volume control .
     NFB-10ES :  Built in 32 steps relays based volume control.
3,  NFB-10ES2:  With full function remote control.
     NFB-10ES: Non remote .
What's improved  in the NFB-10ES3 from the NFB-10ES2?
1, Upgrade the chassis .
2, Upgrade to 4 groups digital inputs (Coaxial RCA / Coaxial BNC / Optical / USB)
3, More outputs ports available in DAC mode and Preamp mode, and they can be connected simultaneously. (XLR*2 , RCA *2, ACSS *1) .
4, OCC wires .

Fully balanced design built by discrete analog stages without any OPA and couple caps in the signal channels , built in real balanced DAC, can output for headphone, as DAC (fixed output ) and preamp (variable output )
Non- feedback ACSS analog output stage .
Applied LED display, avoid the RF disturb as LCD display for better sound quality
R-core transformers and Hi-fi grade parts like DALE resistors, WIMA caps .

Total of 6-group PSUs are used to purify the power supply , the analog amp have discrete PSU power supply
Four-channel digitally controlled relay-based volume control to avoid channel imbalance and improve sound quality. NFB-10ES2 has 80 steps volume level control in both high gain mode and low gain mode. The total 160-step volume control ensures smooth control of the volume level.
4 channels digital input :
  Coaxial RCA / Coaxial BNC / Optical / USB
DAC output :
  XLR*2 / RCA*2 / ACSS  (User can setting with either variable and fixed output level )
Headphone output : 4 pins XLR / 6.3MM SE
USB Audio Class 2 High-speed Input from Windows / MAC / Linux
Supports High / full speed Asynchronous Transfer Mode up to 384K / 32Bit ability .
Resolutions support 16 / 24 / 32 Bit with sampling rate support 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, 192kHz


If only the RCA or 6.3MM headphone  is used, is the NFB-10ES3 being wasted or not fully utilized?
       NFB-10ES3 is a real balanced DAC . It has balanced output (ACSS, XLR and balanced headphone output) and single-ended output . There are 4 ACSS amplifiers in the NFB-10ES3 for balanced outputs and balanced inputs. Even when a single-ended output is used, the ES9018 DA chips will perform fully thanks to the fully balanced design.

12th Aug , Thierry :

         I received my nfb-10es2 in perfect condition, thank you.
         Sir, I think you are a magician in electronics.
         I had never heard such a sound realism, what truth and the highs are incredibly true. It's a shock for me.
         Thank you again for this great work.

28th Aug ,  Klósz :

         I have got the DAC. What could I say?

         Superb. Unbeatable price/sound quality rate. I am astonished.

         Thank you for your help and your great DAC!

English:
         I received NFB10ES2 in good condition .

         The sound is very clear, precise and very natural .

         Low frequency are really sharper and detailed

         Actually all frequency are really beautiful

         It is a real pleasure to listen to music with this device

        Thank you for your work Audio GD!

French:
        j'ai reçu le NFB10ES2 en très bonne condition

        le son est très clair , précis et très naturel

        les basses fréquences sont vraiment plus net et détaillé

        en réalité toutes les fréquences sont vraiment très musical

        on obtient un son bien plus clair et pourtant sans dureté le son coule bien plus que dans mon ancien DAC ( c'est très fluide quoi ^^ )

        le placement sonore est très précis lui aussi

        c'est un réelle plaisir d'écouter de la musique avec cette appareils

        le rodage de l'appareils me donne l'impression d'encore plus de clarté, toujours sans dureté ou sur brillante

        pourtant je ne suis pas très croyant en ce qui concerne le rodage

        mais certain ploc au changement de source (hp ou casque ) ou gain semble bien disparaitre de plus en plus avec l'utilisation de l'appareils ( certain on déjà complètement disparu ... donc a priori ça ce rode ^^ )

        j'ai le modèle avec TCXO les qualité de l'usb sont indéniable c'est via ce port que j'arrive au son le plus clair et détaillé ( ce qui changerai peu être avec une très bonne platine cd mais les sortit optique/coax de ma platine sont médiocre )

        Merci pour votre travail Audio GD!
