AUDIO-GD R-1 NOS DAC Discret R2R DSP FPGA USB Amanero HDMI I2S 32bit 384kHz DSD512 Noir - avis - Il y a 4 avis.

Très belle restitution sonore
Niveau son , la qualité est au rendez-vous. Il remplace un Dac Oppo Sonica (modifié Audiocom) de 2017 qui valait 3000 euros à l’époque.
Ce dac est même d'un niveau supérieur à l'Oppo, avec plus de naturel dans les voix et plus de texture et richesse dans les instruments. La spatialisation est large et profonde. Cependant il est un peu moins précis et définit que l'Oppo qui est équipe d'un dac sabre 9038 pr, mais l'ecoute est moins fatiguante sur des titres mal enregistrés.
A noter quand même que le descriptif est erroné , ainsi que la notice sur le site Audio gd. Ce dac est NOS et il n'y a pas de fonction de sur-échantillonnage, d’où une étoile en moins.

Beautiful quality DAC
I bought this DAC as an addition to my system following an advice from one of the most experienced audiophiles of my country. I asked for the best DAC around 1000 euro.
My setup: Spendor A7 speakers, Unison Research Unico Secondo amp with Sylvania NOS tubes, Eversolo DMP A6 streamer, AQ Rocket 44 speaker cables, Synergistic Research Basik XLR.
I replaced the internal DAC of Eversolo A6 by this Audio-gd R1 NOS hoping to get a better sound than the detailed but thin sound and the bloated bass. I bought also a Neotech Neub-1020 OCC silver USB cable to connect the new DAC.
I listened for three months and the conclusions are:
-much fuller bodied sound
-clear on all frequencies from deep bass, superb medium to highest hights
-natural voices like real singers
-tight round bass
-scaled music from delicate to blow your speaker rock
-sense of dark silent back
-sense of space between instruments
-sense of big sound.
Of course, good sound is obtained only when the speakers are proper positioned and angled, beside good gear.
Totally happy with this DAC. Audio-gd is not about marketing but about real quality.
Recommended.

Incredible DAC!
OK, cons first:
1/ clicking sound on digital coax cable connection when you switch from one sample rate material to another also from PCM to DSD.
This issue is not present on HDMI/I2S cable connection. Strange.
2/ Ridiculous burn-in time. DAC straight from the box sounds like broken one. Muddy, unclear, unpleasant. And all of this despite 100 hrs factory burn-in. I would send it back to seller, but before the purchase I made deep online research and all R1NOS users advised long burn-in time: minimum 600 hours. So I gritted my teeth and gave this DAC a chance and time to spread the wings.
It was real rollercoaster. One day DAC was sounding OK, another day excellent, next day - really poor.
But after approx 400 hours of burn-in sound started to be more stable and after 610 hours - just incredible!
Anyway: I've purchased this DAC 12/4/2025 and I'm able to use it normally just since yesterday: 21/7/2025. 600 hrs of burn-in is a MUST!
Now - pros:
1/ plenty of connection possibilities, including HDMI/I2S (best one!). Strongly advise to use this one! You will avoid clicks and the sound is definitely best.
2/ SOUND!!! Just unbelievable! Sweet, refined, rich, saturated, airy, delicate, nuanced, crystal clear. My system sounds like minimum 50 000€ stack and I paid in general approx 7000€ for all (some elements new, some second hand). Detail? Well... this is not delta/sigma. If you want detail, buy ESS. There will be detail, but there will be no music at all. This DAC is typical R2R - detailed enough. Anyway - for example articulation of guitar strings is fully satisfactionable.
I have just 2 things more to say:
1/ in its price this DAC is a STEAL!!! Totally non fatiguing yet absolutely crystal sound.
2/ this is cheapest Audio-gd DAC. If the price floor in this factory has so incredible quality, I would like to see the ceiling...
HIGHLY RECOMMENDED!!! (if you're happy to wait 600 hours)

Good job, Audio-gd! :)

Naturel
Super service de la part d’Audiophonics, bravo pour votre rapidité de traitement et votre offre.
Concernant le dac R2R Nos : musical, naturel, les détails sont là sans être envahissants, rythme, bref du plaisir dans la matière à partir de musique dématérialisée. J’ai aussi un Chord Hugo 2 qui m’amuse beaucoup mais me fatigue parfois. Écoute casque uniquement. Construction solide avec les fonctions de base sans avoir besoin d’un écran 15 " qui brille comme un sapin de Noël. Je recommande.
