Sound Characteristics:

    "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.
