The headphone output of the d1-integral-headphone has been optimised to be able to drive high end headphones.

"totaldac + Roon = Happiness
What do you get when you combine a totaldac and Roon and Tidal HiFi? Endless enjoyment."

Totaldac is the only brand mentioned 4 times in the Audiostream favourite short list. Michael Lavorgna, AUDIOSTREAM (Stereophile)
"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.
And let’s not forget about a very specific, unique headphone out, designed to meticulously show what Vincent Brient achieved on a d/a conversion field.
Then no criticisms are due where his d1-integral-headphone performed so exceptionally well."
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

Totaldac d1-integral-headphone schematics

Embedded DAC interfaces:
-192KHz asynchronous Xmos USB, optical, RCA and AES-EBU digital inputs, selectable from a remote control.
-44.1KHz, 48KHz, 88.2KHz, 96KHz, 176.4KHz and 192KHz, 16 to 24 bit formats supported.
-as an option, DSD (DoP standard) supported on all the inputs.
-embedded custom clock with anti-jitter FIFO memory.
-3Vrms max RCA . The XLR connector carries only the un-balanced signal, so it is equivalent to the RCA output.
-6.35mm jack output for 15ohm to 600ohm headphone. 3Vrms output, 1.2W peak under 15ohm still far away from amplifier saturation.
-volume control, adjusted by a remote control and an OLED display, works for all inputs, not only USB.
-phase polarity selected by remote control.
-non-oversampling DAC compensation filter activated or disactivated by remote control.
-display switched off by remote control or automatic.
-R2R DAC technology using 0.01% Naked Bulk Metal® VAR Foil resistors from Vishay Foil Resistors, 100 resistors are used.
-class A discrete transistor output stage taken from the d1-six.
-external power supply to minimize the noise on the embedded preamp.
-aluminium and PMMA enclosure with massive pure copper antivibration plate.
-power consumption 22W max.
-dimensions: height 110mm, width 360mm, depth 290mm.
-power supply dimensions: height 65mm, width 122mm, depth 180mm.
-weight: 6.5kg.

Computer interfaces and available applications:
All computer interfaces and applications are exactly the same as those given for the d1-server.

Available options:
-DSD (DoP).
-silver massive aluminium front panel.
-115V or 100V power supply.
