D1-Player

About the D1-Player

The TotalDAC D1-Player is a premium digital-to-analog converter (DAC) designed with R2R ladder technology using 100 pieces of 0.01% VAR Bulk Metal Foil resistors from Vishay. It supports asynchronous USB (up to 192kHz), coaxial RCA, AES-EBU, and optical digital inputs, selectable via remote control. The DAC handles PCM formats from 16 to 24 bit and sampling rates from 44.1kHz up to 192kHz, with optional DSD (DoP standard) support on USB, AES-EBU, and SPDIF inputs. It features an embedded custom clock with anti-jitter FIFO memory to reduce jitter and improve sound quality. The analog output stage is a class A discrete transistor design, delivering up to 3.5Vrms on RCA and 7Vrms on XLR outputs, with a headphone amplifier supporting 32 to 600 ohm headphones. Volume control, phase polarity, and a non-oversampling DAC compensation filter can be adjusted via remote control and displayed on an OLED screen. The unit is housed in an aluminum and PMMA enclosure with a massive pure copper antivibration plate and powered by an external power supply to minimize noise. Dimensions are approximately 110mm high, 360mm wide, and 290mm deep, with a weight of about 7kg. Optional upgrades include live-power grade power supply, silver front panel, BNC coaxial input, DSD support, and bass boost.
