A fully balanced design built with discrete analog stages without any opamps or coupling caps in the signal channels
It has a built in balanced DAC and can act as a headphone amp, a DAC (with fixed output) and preamp (with variable output )
Non-feedback ACSS analog output stage .
Applied LED display which avoids RF interference inside the unit.
R-core transformers and Hi-fi grade parts like DALE resistors, WIMA caps .
A total of 6 PSU groups are used to purify the power supply and the analog amp has its own discrete power supply.
A four-channel digitally controlled relay-based volume control to avoid channel imbalance and improve sound quality. The NFB-10ES2 has an 80-step volume level control in both high gain mode and low gain mode. The total 160-step volume control ensures smooth control of the volume level.
3 digital inputs: coaxial S/PDIF, Optical and USB
DAC output : XLR / RCA / ACSS (User can setting with either variable and fixed output level)
Headphone output : 4 pins XLR / 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 .
Resolutions support 16 / 24 / 32 Bit with sampling rate support 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, 192kHz
Memorizes all settings and it could resume the last settings when power on.
