Fully balanced design built by discrete analog stages without any OPA and couple caps in the signal channels.
Non- feedback ACSS analog output stage .
Uses three R-core transformers (135W total) separate power supplys for the digital part , right channel and left channel.
More than 50,000uf audio grade NOVER capacitors are used to ensure ample and smooth power feed.
A total of 15 class A PSU groups are used to purify the power supply. To achieve high S/N, the control circuit is powered with separate regulator.
Uses most Hi-end grade parts and exact match transistors.
5 channels digital input : AES / BNC coaxial / RCA coaxial / Optical / USB
DAC output : XLR / RCA / ACSS
USB Audio Class 2 High-speed Input from PC/MAC
Supports full speed Asynchronous Transfer Mode
Resolutions support 16 / 24-Bit with sampling rate support 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, 192kHz
Supports up to 24Bit/192KHz
Supports 2X , 4X and 8X oversampling customers setting
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
Uses most Hi-end grade parts
Uses mostly DALE and Vishay resistors, WIMA ,EVOX capacitors and a lot SOLEN caps. The electrolyte capacitors are custom ordered from NOVER (a UK brand), and exact-matched transistors. RCA sockets are custom ordered and 24k gold-plated, the power socket is RA 24k gold-plated. Neutrik balance sockets and Canare BNC socket .All transistors are Toshiba and Hitachi.
If only the RCA is used, is the NFB-9.2 being wasted or not fully utilized?
NFB-9.2 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-9.2 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.
NFB-9.2 have 3 feet under bottom side for the best balance state , if customers want 4 feet , please ask the custom order .
