主要技术规格

-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.

-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 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.

-possibility to connect a headphone with an impedance higher than 60ohm and with xlr connectors directly to the balanced XLR output of the DAC. A way to get 6.2Vrms and get 4 times more power. Also allows to listen directly a headphone with the dual DAC option, a Sennheiser HD 800, an Audeze or a AKG K701 for example.

-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.

-weight: 6.5kg.
