AUDIO-GD NFB-11 (2015)
DAC / Headphone Preamplifier / Amplifier
Versatile, efficient, and very affordable ...
A true Swiss audiophile knife, this NFB-11 combines the functions of DAC, preamplifier, and headphone amplifier, just that.NFB is the acronym for Non-Feedback, a technology used by Audio-GD so that it does not "color" the sound at the output stage electronics, thus providing a more neutral sound than professional.
A modern USB interface
The integrated ES9018 SABER allows you to manage 32Bit / 192kHz sources in both SPDIF and USB, and up to 384kHz in USB. In order to use the NFB-11 on Windows via its USB-B input on the rear panel, you must first download the USB-32 Driver, available on the Audio-GD website: ef = "http://www.audio-gd.com/Pro/dac/USB32/USB32EN.htm" target = "_ blank">USB-32DSD (DSD64, DSD128, DXD support)
Stunning sound reproduction:
32bit / 384kHz / DSD / DXD / TCXO
The 100% discreet design of this preamplifier (no PDO) is backed by a high power supply capable of providing the necessary energy. The ALPS RK27, the 24K Gold Plated RCs, and the Nover (UK) capacitors have fhas been specially manufactured on Audio-GD specifications. The Toshiba and Hitachi transistors were manually paired.
TCXO - 100MHz
Usually the Audio-GD devices are equipped with the standard 80MHz clock, except this Audio-GD NFB-11 includes the 100MHz TCXO Ultra Low Jitter option, perfectly associated with the ES9018. This TCXO (Temperature Compensated X (Crystal) Oscillator) clock is more precise and significantly reduces the jitter.
SABER ES9018
This DAC / Preamplifier / Headphone Amplifier High Fidelity is equipped with the famous ESS ES9018 32 bit / 384kHz. This conversion chips is capable of reading high definition formats from DSD to PCM. The NFB-11 has a "Mute" switch on the rear panel, stamped with 1 or 2. It is dedicated to playing DSD files. Set it to 1 to enable Mute Design (DSD file playback). Set it to 2 for playing PCM files.
