AUDIO-GD R-1 NOS DAC Discret R2R DSP FPGA USB Amanero HDMI I2S 32bit 384kHz DSD512 Noir - avis - Il y a 3 avis.

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.
