DAC / Headphone Preamplifier / Amplifier
Here is the "new" version of the NFB-27, taking the qualities of the NFB-7 and the MASTER 9. This version is the last born of the NFB family, acronym which means "Non-Feedback".
Non-Feedback is the technology used by Audio-GD so that it does not "color" the sound at the level of the output stage electronics, providing you with a sound of professional neutrality.
This device has a DAC SABER ES9018 supporting signals up to 32bit / 384kHz and DSD in USB, all thanks to the new asynchronous AMANERO 384 combo interface of the manufacturer. In order to use the AMANERO correctly, here are the indications of Audio-GD as well as the download link of the driver:f = "http://www.audio-gd.com/Pro/dac/Amanero/AmaneroEN.htm" target = "_ blank">Amanero Combo 384 USB Interface.
The NFB-27H has 8 inputs: XLR / RCA x2 / USB / Coaxial / BNC / I2S via RJ45 / Toslink Optics, alongside 3 outputsAnalog: XLR / RCA / RCA. Including the DAC and Preamplifier outputs: XLR / RCA, as well as the 4 outputs Headphones: 1x XLR 4 PIN (ACSS) / 2x XLR 3 PIN / 1x 6.35mm stereo jack.
The 100% symmetrical and discreet design of this converter is backed by 5 groups of Class A power supplies. 24K Gold Plated RCA Plugs as well as Nover (UK) capacitors have been specially manufactured on specifications audio-GD.
The NFB-27H, in addition to all the rest, has a TCXO Audio-GD internal clock directly integrated into the system significantly lowering the jitter, as well as internal wiring designed entirely in OCC copper.
This NFB-27H is accompanied with its metal remote control, brushed aluminum finish. All the sobriety and class of Audio-GD stand out from this remote, as it is purified and functional. You will find 2 buttons to change your input sources, as well as 3 buttons to adjust the volume: Plus / Minus / Mute.
This SABE ES9018 conversion chipset built into the NFB-27H is one of the first generation 32bit converters capable of reading High Definition signals up to 32bit / 384kHz, not forgetting the DSD and PCM files. It is recognized as one of the most efficient and effective converters. You can find all its detailed documentation on the official website of ESS:
