The world's finest separate digital source playback system, designed to meet the challenge of capturing all the potential of the Super Audio CD format.

The world's first monaural D/A converter - designed to bring out the full potential of the Super Audio CD format. (* Available 2004 Aug.)

  • Input terminals: XLR (2 systems), RCA (1 system), IEEE1394 (2 systems).
  • Super Audio CD DSD signals are input through the IEEE1394 input terminal or the XLR1 input terminal (ESOTERIC proprietary ES-LINK format).
  • PCM format signal can be input up to 192kHz (DUAL transformation or STEREO transformation).
  • When the signals output by the player are either STEREO or MULTI-CHANNEL, the unit outputs the channel as selected by the MENU.
  • There are 3 digital filters to choose from: FIR, RDOT, FIR+RDOT. The digital filter can also be turned completely off. The signal is converted up to 768kHz before being sent to the multi-bit D/A converter chips, Burr-Brown PCM1704s. Super Audio CD DSD signal is converted either to 88.2kHz or 176.4kHz, before inputting to the digital filter.
  • Signal output from the digital filter streams into D/A converter IC through a FIFO (fast in/fast out) circuits, which reduces signal jitter.
  • The D-01 is equipped with 8 D/A converters per unit (24bit Multi-bit D/A converter: PCM1704). With the use of 8 DACs per unit, S/N ratio and linearity is greatly improved. This DAC configuration results in very precise musical expressiveness and enhanced ambience, presence and transparency.
  • ESOTERIC uses 42V discrete power circuit construction in the driver circuits for analog signal outputs. This very high rail voltage produces prompt circuit drivability and excellent transitional rates.

Word synchronization

Jacks on rear panel The D-01 is further enhanced by the inclusion of word sync outputs/inputs. The D-01 can output or input word clock signals at any of the following frequencies:
44.1/88.2/176.4/48/96/192/48P/96P/192P/100/100P kHz (P means 4% down mode for PAL FILM).
The D-01's Rb IN mode uses a PLL circuit that is highly specialized for a high accuracy clock signals.
The D-01 itself uses a high precision crystal clock that generates ±3ppm of accuracy. The D-01 can input an ultra-precise clock from the ESOTERIC G-0Rb master closk generator, which will further enhance the delicacy and articulation of the material.

Excellent grade 6N pure copper conductors for main internal wiring

AC power cable and most internal wiring are 6N pure copper conductors for pure, high resolution sound quality. 6N cable outer jacket is Polyolefin PVC free material. None of the other wire jackets include PVCs to protect against environmental pollution.

Equipped with a high-grade analog volume attenuator/Directly connectable to a power amplifier

Analog volume attenuator enables volume attenuation without loosing digital information.
The volume circuit can be bypassed for use with an external preamplifier.

Highly rigid body construction eliminates harmful external vibration

Thick aluminum is used on the top, side and front panels to block vibration. The sound pressure from loudspeakers could easily affect the top panel of the D-01 so it is constructed from 8mm thick, brushed aluminum. The chassis is supported by four Pinpoint feet (patent pending), allowing the unit to be mechanically isolated from its environment. The front panel is designed to be highly elegant with a brushed finish and curved corner design. All these features contribute to a sense of quality found only in the world's finest D/A converter.
