Fully balanced design built by discrete analog stages without any OPA and couple caps in the signal channels.
Non- feedback ACSS analog output stage .
Total of 7-group dedicated power circuits are used to purify the power supply.
Four-channel digitally controlled relay-based volume control to avoid channel imbalance and improve sound quality. NFB-10SE has 48 steps volume level control in both high gain mode and low gain mode. The total 96-step volume control ensures smooth control of the volume level.

Memorizes all settings and it could resume the last settings when power on.
"Neutral but smoothness sounding ,it doesn't sound skeletal or digital (or metallic). There's meat aplenty on them bones . It's a sigma-delta DAC chip implementation without the dryness, neutrality without the emotional disconnection" - John Darko
If only the RCA or 6.3MM headphone is used, is the NFB-10 being wasted or not fully utilized?
NFB-10 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-10 for balanced outputs and balanced inputs. Even when a single-ended output is used, the “Dual WM8741” DA chips will perform fully thanks to the fully balanced design.
