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.
