"The D1-Dual DAC is one of the finest sounding DACs I've had the pleasure to live with and listen to.
So natural, so life-like, it leads you directly to the music being played with very little reminder that you are in fact listening through a hi-fi. Stunning."
Totaldac is the only brand mentioned 4 times in the Audiostream favourite short list.
Michael Lavorgna, AUDIOSTREAM (Stereophile)
"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 review
"BEYOND YOUR IMAGINATION", Audio Art article (Taiwan) english translation , original chinese version
"...impresses from the first notes with expansive soundstage and bold contours. Tonality is rich and very natural.
Totaldac is the most 'analogue' sounding DAC I heard. And by 'analogue' I mean vinyl like raw character rather than sweet & round.
If you're alergic to 'digital' sound, this maybe the DAC you're looking for. Overall score: 9.5/10" Marcin from Jplay
"These d1-server + d1-dual or d1-tube set-ups attained a level for PCM and DSD which I’d not heard before.
After this review, the prize "Grand Frisson 2014" of Audiophile Magazine is obvious." Thierry Nkaoua, Audiophile-Magazine and 6moons
"I don’t have firsthand experience of all other super DACs out there but the Totaldac D1-Dual DAC is the best sounding digital playback I’ve had in my home." Key Kim, Stereo times
"The only DAC listed in "REFERENCE SYSTEM"" MONO&STEREO
"This DAC is now used in our reference system.", haute fidélié
-192KHz asynchronous Xmos USB, optical, RCA and AES-EBU digital inputs, selected from a remote control.
-44.1KHz, 48KHz, 88.2KHz, 96KHz, 176.4KHz and 192KHz, 16 to 24 bit formats supported on all inputs except 96KHz max for optical input.
-as an option, DSD (DoP standard) supported on the USB, AES-EBU and spdif inputs.
-USB input compatible with Jplay in 24 bit "extreme hibernate" mode.
-embedded custom clock with anti-jitter FIFO memory.
-3.1Vrms max RCA, 6.2Vrms max XLR analog output and 32ohm-600ohm 3.1Vrms max headphone amplifier.
-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% VAR Bulk Metal® Foil resistors Vishay Foil Resistors, 200 resistors per stereo channel.
-dual DAC option included, using 2 DACs per channel for a 100% balanced DAC. Upgrades the XLR output only. A special XLR to RCA is available as an optional extra to get the dual DAC sound to an amplifier with RCA inputs.
-class A discrete transistor output stage for the d1-dual DAC.
-external power supply to minimize the noise on the embedded preamp.
-aluminium and PMMA enclosure with massive pure copper antivibration plate.
-power consumption 21W.
-DAC dimensions: height 110mm, width 360mm, depth 290mm.
-power supply dimensions: height 65mm, width 122mm, depth 180mm.
-DSD (DoP) option.
-silver massive aluminium front panel.
-115V power option.
-BNC coaxial digital input instead of RCA.
-D2-dual, 69 bit 2 way active crossover including a digital preamp for the main volume control and also for the relative level between bass and treble. The bass channel uses two RCA connectors for stereo without dual DAC option or in mono with dual DAC option. The mid-high channel uses RCA and xlr (balanced) connectors, with dual DAC option. The crossover slope can be 6dB/oct, 12dB/oct or 18dB/oct. All parameters, crossover frequency, filter slope, relative volume, main volume, relative digital delay... can be controlled from the remote while listening to music. The subwoofer output can be mono-balanced on demand instead of stereo.
With the d2-dual with DSD option the digital delays can't be used.
-2, 3, 4 way active crossover or more, with or without dual DAC option, by associating several DAC boxes.
-pair of XLR to RCA adaptor in an external box, special "dual DAC", 3.1Vrms output.
-USB cable with high performance filter for a noticable sound quality improvement.
The list of embedded options is on the serial number sticker on the rear panel of the DAC.
