Audio-GD - NFB7.77 - Discrete Balanced Dual ES9038 PRO FPGA Accusilicon DAC - PCM / DxD / DSD)

NFB-7.77 is Audio-GD's flag-ship - dual -  Sabre ES9038Pro based Digital Analogue Converter. An additional FPGA was implemeneted to separate the data feed to each dual ES9038 Pro in mono mode. It re-clocks and FIFO's all incoming signals to make sure the output data is (almost) free from jiter and reaches optimal timing with its source clock. The FPGA design includes a high performance SPDIF interface, replacing the less good SPDIF interface of the ES9038 Pro .

All parts and components are selected based on excellent sonic and measurements performance. Components are e.g. from DALE resistors (USA), WIMA capacitors (Germany)  and NOVER parts (UK) . The used components but also the technical design (e.g. discrete analogue section and high speed FPGA's) of this system were being selected after many years of experience and practices and are considered to perform and provide sublim sonic results. Supporting todays high resolutions and up to date interfaces like USB and I2S.

*** FREE 3 X Accusilicon AS318B Femto Clock UPGRADES ***

Enjoy DSD512 and best sound quality with Singxer F1 USB module installed (Replacing Amanero)

Dual ES9038 Pro design, one per channel in mono mode, this improves the channel crossover and soundstage is larger and extremely precise.

Enjoy DSD512 and best sound quality with Singxer F1 USB module installed (Replacing Amanero)

MAGNA HIFI is offering a significant upgrade of the internal USB interface by replacing the Amanero USB interface for a more sophisticated Singxer F-1 XU208 board using the Crystek CCHD-575 ultra low phase noise clocks. Besides the sound quality improvements it enables native DSD512 support! We'll make sure the Singxer F-1 is properly installed and using internal ultra clean power source from the internal DAC to ensure best sound quality

The filter Settings are for personal preference. The default setting is typically the best for most listeners. Feel free to adjust it according to your preference after you are familiar with the sound. IIR stands for Infinite Impulse Response. These settings will likely not offer significant sonic difference.
