d1-six DAC or DAC/streamer

Compared to the d1-dual, the d1-six uses 6 channels of discrete R2R ladders instead of 4 ladders for the d1-dual.
The sound quality is optimum on the XLR output as well as on the headphone jack and on the direct RCA output.
This DAC can integrate the streamer board for a direct network use, to listen local files or for streaming use.
All d1 DACs can be upgraded to a d1-six.

"You probably won’t be amazed at the sound of d1-six DAC when listening to it at the beginning. However it only takes the time of one afternoon for you to find yourself in love with it - the charm of the natural, smooth and pure sound that flows with the melody at every moment. The vivid and exquisite sound performance, which makes the audiences feel relaxing yet emotional, as once again demonstrated the French excellent gift of manufacturing high-quality audio equipment."

Totaldac d1-dual rear

Silver option:

d1-six inside, with server/streamer option:

Spectrum of a 1KHz waveform, same FFT reference as for the d1-dual for a direct noise floor comparison:

The noise floor is very low (even lower than with the d1-dual).

More reviews, about the old little brother d1-single:
"d1-single-mk2 is an extremely good DAC. It delivers a precise, resolving sound, but also slightly warm and vivid.
It is very clean and differentiates recordings really well.
Vincent's DAC though sounded great when combined with my Soulution 710 power amplifier.
Was it just a coincident that these two devices worked so well together?
I don't know, but this power amp usually sound better paired with active preamps.
This time, the elimination of the Ayon Spheris III from signal's path resulted in a more direct sound.
The leading edge was faster and clearer. The front of the soundstage was brought closer to me and the back even further away, which created the effect of extended soundstage." Wojciech Pacula, High Fidelity
"totaldac + Roon = Happiness"

Michael Lavorgna, AUDIOSTREAM (Stereophile)
"What an enjoyment. A beast of musicality."
Maximum note 8/8 for 5 sound qualities. Note 7/8 for the two other sound qualities. Dominique Mafrand, haute fidélité, about the mk1
"The degree to which it bested what I knew (including APL Hifi, Audio Aero, dCS, EMM Labs, Esoteric, Weiss, Meitner and Zanden) was unexpected" Srajan Ebaen, 6moons, about the mk1
"Vincent’s product sounds very refined, balanced, coherent, neutral and is very analogue overall, lifelike, mildly soft and pleasant.
It doesn’t put additional light on any particular aspect in music, neither it elevates soundstage width, nor saturation or dynamics.
It doesn’t tinker with contouring or tonal balance. It simply isn’t showy in any regard." Dawid Grzyb, Hifi Knights and 6moons
"Recapturing all I think that this Totaldac has marked a before and after on the way I see the DAC world,
reaching levels of naturalness that I only could hear on some top vinyl systems.
This is the perfect DAC model to encourage all vinyl lovers to explore and even change the way they listen to music.
I am convinced that many of them will not return back for sure." Yago, Old & New Sound
"Beyond exciting"
"Totaldac D1 integral is the truly talented one in hifi world´s Idols.", Jussi Arvio, Hifimaailma Magazine, Finland
"If I had to use one word to describe the sound, I'd have to say human.
It reproduced the electronic signal in an organic, tactile, and musical way that I often shook my head at in how similar it was to vinyl.
It doesn't sound like analog, it just sounds analog, albeit different.", Rafe Arnott, part-time audiophile
