USB Amanero Combo 384

Equipped with a USB interface Amanero Combo 384 rather than a USB32, celit offers both optimal performance and compatibility. It supports sampling rates up to 32bit / 384kHz as well as the DXD, DSD64 and DSD128 (DSD256 and DSD512 on Windows). Its design allows it to enjoy a very low jitter.

A breathtaking sound reproduction

Non-Feedback and ACSS

The NFB11.28 delivers optimum performance through carefully chosen components. In addition to supporting the DSD / DXD and sampling rates of up to 32bit / 384kHz, it benefits from the NFB (Non-Feedback) technology developed by Audio-GD on the ACSS stage.

This allows the NFB-11.28 to offer a lower color tone and consequently a faithful reproduction, a very low distortion and a great linearity. You gain in dynamics, details and neutrality.

TCXO 100MHz

With its 100MHz TCXO clock associated with the ES9028 Saber converter, this NFB-11.28 offers an Ultra-Low jitter for ever higher performance.

Sabre ES9028Pro

The NFB-11.28 now includes an ES9028Pro DAC ESS to convert digital signals to analog. This allows output sample rate support up to 32bit / 384kHz and a Signal / Noise ratio of 118dB.

It brings significant improvements in comparison to its predecessor (ES9018) as a compensation for the harmonic distortion rate of the analog output through the 32bit processing block, an improvement in the over-sampling filters, the phase-locked loop forgreater precision or even distribution of the feed.

High-end components

All of the components have been carefully selected to offer a device that is as efficient as it is durable. Thus, for example, you will find an ALPS 27 potentiometer or pure copper RCA plugs.

Petit boitier magique...
Je recherchais un nouvel ampli casque pour mon Sennheiser HD600, et là, à moins de 400 Euros le AUDIO-GD NFB-11.28 est un petit boitier miracle, bien construit, solide, des connectiques de qualités.
A l' écoute, dynamisme et définition, le champ stéréophonique est d'une excellente facture pour le HD600.
Comme préamplificateur entre mon lecteur CD et mon ampli de puissance le DAC ES9028 TCXO de l'AUDIO-GD NFB-11.28 est parfaitement à la hauteur, voire au dessus d'autre DAC ou préamplificateur.
Je suis très content de mon investissement, livraison rapide, encore merci a l'équipe d'Audiophonics.

AUDIO-GD NFB-11.28
Only a few days in but very happy with this dac/amp. It's my first venture away from on-board pc sound and with a decent pair of headphones (DT770 custom studios) there's a marked improvement in all round clarity and smoothness, as well as having much more volume available now. I'd say the sound stage is wider now also and as there's no distortion the whole package sounds much more refined than using my pc's on-board sound chip did.

My headphones are 80ohm and in either high or low gain setting I've not had the vol dial past 12 o'clock - that is already plenty loud enough and I'm sure this amp will easily drive higher ohm headphones if I wish to purchase some in the future.

I'm on windows 10 and after first installing the drivers from Audio GD's site everything worked flawlessly. The build quality looks very good indeed and so all together, I'd thoroughly recommended this product and also Audiophonics who delivered it within a week to the UK - very good service and I would certainly shop with them again with confidence. Many thanks.

Excellent combo
J'ai choisi ce modèle pour sa compacité et pouvoir le transposer d'un PC à l'autre pour écouter de la musique au casque avec une bonne qualité.
Sur une chaîne de salon, j'ai déjà des grands frères Audio-gd, le dac nfb-3 couplé au nfb-1amp.
Le nfb-11.28 marche fort d'entrée de jeu, après une installation facile du driver Amanero pour l'usb. Que ce soit la partie dac ou ampli casque, il y a beaucoup de matière, de détail, c'est neutre mais les basses sont là et descendent agréablement (équilibre = parfait pour moi), il existe une bonne dynamique générale. Spatialisation à la Audio-gd pour ceux qui connaissent, et les pianos en particulier sonnent très bien (sur des musiques modernes dont du jazz).
Oui il existe une différence sur les modèles de salon, mais pas énorme dans l'absolu. La puce Sabre 9028 me semble apporter une évolution par rapport à la 9018 (+ de clarté, voile en moins?), mais pas au point de courir changer mon dac nfb-3 pour un plus récent chez Audio-gd! Ça donne quand même envie d'un projet nfb-1.38... mais pour plus tard.
