Differences with the NFB-10ES2:
1, The NFB-28 has analog XLR and RCA inputs, and can used as a dedicated headphone amp or preamp.
2, The NFB-28 has 4 digital inputs (Including BNC)
3, The NFB-28 has a larger R core power transformer.
4, The chassis is upgraded with all aluminum construction and a user friendly, rotary volume control.


Fully balanced design built by discrete analog stages without any OPA and coupling caps in the signal channels, built in real balanced DAC, output for headphone (4-pin XLR or 1/4") and line level DAC (fixed output) with preamp (variable output)
Non- feedback ACSS analog output stage .
LED display avoids RF disturbance for better sound quality 
Large 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 has discrete PSU power supply 
Four-channel digitally controlled relay-based volume control to avoid channel imbalance and improve sound quality. 
80 steps volume level control in both high gain mode and low gain mode. 160-step volume control ensures smooth control of the volume level.
4 digital inputs: 
  Coaxial RCA / Coaxial BNC /  Optical / USB
2 analog inputs:  XLR / RCA
DAC output: 
  XLR / RCA / ACSS  (User can set either variable output level as preamp or fixed output level as dedicated DAC )
Headphone output : 4 pin XLR / 1/4" (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 ( USB interface ) . 
Supports Resolutions of 16 / 24 / 32 Bit with sampling rates of 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, 192kHz

Used single ended (1/4" headphone jack or RCA output), is the NFB-28 fully utilized?
      NFB-28 is a real balanced DAC. It has balanced outputs (ACSS, XLR and balanced headphone output) and single-ended output .There are 4 ACSS amplifiers in the NFB-28 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.
