d1-single DAC

NEW / DSD READY

d1-single is a simplified version of the d1-dual DAC. It uses one R2R aldder DAC per channel (two for the d1-dual) and it has no balanced output. The USB input is also slightly simplified compared to the d1-dual.
A DSD (DoP) option is available for the USB, spdif and AES-EBU inputs.

"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
"With the performance of this device you can抰 avoid the emotion. Its ability to play even the most complex signals of the Big Band is really impressive. A great DAC indeed." Angelo Jasparro, AUDIO-ACTIVITY

Totaldac d1-single front

-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 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. The USB input have been simplified compared to the d1-dual USB input.
-embedded custom clock with anti-jitter FIFO memory.
-3.1Vrms max RCA and 32ohm-600ohm 3.1Vrms max headphone amplifier. The XLR connector carries only the un-balanced signal, so it is equivalent to the RCA output.
-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.
-all unused inputs are completely disconnected (including the ground) to keep the optimum noise floor even when several sources are connected.
-R2R DAC technology using 0.01% VAR Bulk Metal� Foil resistors from Vishay Foil Resistors, 100 resistors per stereo channel.
-class A discrete transistor output stage for the d1-single DAC.
-external power supply to minimize the noise on the embedded preamp.
-aluminium and PMMA enclosure with massive pure copper antivibration plate.
-power consumption 18W.
-DAC dimensions: height 110mm, width 360mm, depth 290mm.
-power supply dimensions: height 65mm, width 122mm, depth 180mm.
-weight: 6.5kg.

Available options:
-DSD (DoP) option.
-silver massive aluminium front panel.
-115V power option.
-BNC coaxial digital input instead of RCA.
-d2-single and d3-single, 69 bit 2 way or 3 way active crossover with RCA analog outputs including a digital preamp for the main volume control and also for the relative level between bass and treble. 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.
With the d2-single with DSD option the digital delays can't be used.
The d3-single is not compatible with the DSD option (you can use a reclocker or d1-server as a DSD to PCM converter).
-USB cable with high performance filter for a noticable sound quality improvement, length on demand, 1m by default.
The list of embedded options is on the serial number sticker on the rear panel of the DAC.

1KHz -110dBFs sinewave 20Hz-22KHz spectrum at the RCA output:

FFT 1KHz -110dBFs single DAC

The measurement is done with USB as source, from a standard computer plugged on mains.
The noise floor is very low especially in the 200Hz-4KHz region where the ear is very sensitive.
