Audio-gd NFB-9.2

  • 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.

    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
    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.
    Note:
    NFB-9.2 have 3 feet under bottom side for the best balance state , if customers want 4 feet , please ask the custom order .
