AUDIO-GD R2R 11 (2017)

DAC / Preamplifier / Headphone Amplifier Audio-GD R2R 11

Versatility and efficiency

The Audio-GD R2R 11 is THE Swiss army knife for audiophiles. Combining the functions of DAC, Preamplifier and Headphone Amplifier, it will fulfill most needs./ P>

Embarking many new features, this new version of the acclaimed NFB11 now offers a discrete R2R DAC, a USB Amanero Combo 384, a dual-stage power supply, selectable digital filters and an MCU controller.

USB Amanero Combo 384

Equipped with a USB interface Amanero Combo 384 rather than USB32, it offers both performance and compatibility. It supports sampling rates up to 32bit / 384kHz and 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 R2R 11 offers optimal performance thanks to componentss chosen carefully. Thus, in addition to supporting the DSD / DXD and sampling rates up to 32bit / 384kHz, it takes advantage of the Non-Feedback (NFB) technology developed by Audio-GD on the ACSS stage. This allows the converter to offer less sound color and therefore a faithful reproduction, a very low distortion and high linearity. You gain in dynamics, details and neutrality.

R2R

DA-8 x2

The NFB-R2R 11 now features a dual discrete R2R DAC R2R Specially designed and optimized for converting digital to analog signals. This allows output sample rate support up to 32bit / 384kHz and a 100dB Signal / Noise ratio.

High-end components

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

Pas encore parfait...
Utilisé principalement pour la partie ampli casque.

Son particulièrement chaud, texturé, un rendu très analogique/tube, tout en restant très détaillé et ample. Pas aussi transparent que les modèles en Sabre, celui-ci présente un medium trop coloré à mon gout.

L'ampli peut driver à peu près importe quel casque!

Reste des "pops" clairement audibles en USB lorsque l'on change de bitrate ou simplement que l’on navigue dans une piste. C'est pour cette raison que j'ai décidé de le retourner et aussi parce que je cherchais quelque chose de plus "neutre".

Beautifull Sound, but some trouble
A fantastic project, R2R has a great performance. Some problem on USB interface, where I found "click" noise during track switch (on same file format) and OTG Android compatibility for DSD playng. Minor mechanical problems on chassis...
But the sound is very a surprise for Delta Sigma Dac Users...
