"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 is used, is the NFB-17 being wasted or not fully utilized?
NFB-17 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-17 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.
