Monaural D/A Converter D-01
The world’s first monaural D/A converter –Esoteric D- 01 designed to bring out the full potential of the SACD format.
Model D01VU adds optional and incremental upgrades based on evolving technology that includes a change from 6N copper (99.9999% signal purity), to 8N copper (99.999999 signal purity). 8N copper is used as a replacement for all critical internal wiring. [Please note that the D01 system has been rated "World's Best" long before any upgrade path was developed]. The use of 8N copper is extremely rare and contains less than .01 ppm (parts per million) of metallic impurities. This provides incremental improvement of resolution, soundstage, depth and texture. Specially selected capacitors and resistors are used with the internal wiring update to optimize acoustic transparency and signal refinement. Current owners of the D-01 may have their units optionally and incrementally upgraded to VU status (Chargeable). To insure Esoteric factory expertise, this upgrade can only be done in Japan.
A new 2-channel D/A converter, developed from the high performance Esoteric mono-block D-01 design, without any compromise in sound quality.
Additional features include:
- Analog Devices model AD1955 DAC's driven by differential mode for DSD and PCM signal processing.
- Word Synchronization function with other digital components within the system.
- The P-03/D-03 CD/SACD transport system is extremely versatile, featuring multiple user selectable playback modes. These include CD audio (Redbook) playback, native DSD decoding, PCM up-conversion and Esoteric's advanced PCM to DSD signal conversion.
ESOTERIC is proud to introduce evolutionary components for CD/SACD audiophile playback.
The D-05 DAC supplies extremely natural and "true-to-life" analog signals to the amplifier by using the latest 32 bit digital to analog converter devices. The D-05 is the world's first D/A converter incorporating the "AK4397" Delta-Sigma DAC device from AKM Semiconductor, Inc., This device has full 32 bit processing capability. The "AK4397" was designed combining newly developed high speed / high capacity digital processing components and improved analog processing components. This device provides premium quality sound reproduction on a professional level. The "AK4397" has a superior and precise D/A conversion capability thanks to its fully extended 32 bit processing throughout all stages, including digital filter and the "Delta-Sigma," modulator. This high performance technology is an evolutionary upgrade path from conventional 16 or 24 bit D/A converters. The D-05 incorporates dual mono digital and dual mono analog circuits, with dual mono power supply components to achieve extremely high resolution and superior channel separation. This design follows in the footsteps of Esoteric's D-03 dual mono D/A converter. Word clock input and output is included for use with Esoteric transports or stand alone master clock sync generators.
