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.
