Esoteric 34-bit Dual Mono D/A Converter
At a Glance
A DAC following in the footsteps of the Grandioso D1, with uncompromising audio quality. The D-05X uncompromisingly inherits the DAC design philosophy of the Grandioso D1 flagship device and updates all the circuit components from the original D-05 model to obtain sound quality that should be considered the standard for ultra-high-end devices.

Get to know this product.
It includes a large capacitance power supply with two large toroidal transformers at the core for independent left and right channels. The circuit size of the DAC has been doubled to have four differential circuits per channel. In terms of functionality, the D-05X features ES-LINK4 digital transmission, 34-bit D/A processing, the well-received ESOTERIC-HCLD line buffer from the Grandioso C1 preamp, and the unique ES-LINK Analog line transmission for high audio quality. It also supports playback at high resolutions such as DSD 22.5 MHz to obtain even more outstanding audio playback overall.
34-bit D/A Processing - Dual Mono
8 32bit (AKM 4497) DAC cicuits
Fully discrete Class A buffer amplifiers
up to 8x up-conversion, PCM to DSD conversion
Four digital filters and digital filter “Off” mode
USB supports up to 768kHz/32-bit PCM and up to 22.5mHz DSD
Esoteric-HCLD: Esoteric's Exclusive Output Buffer Delivers Powerful Direct Current Transmission
The ability to produce comparatively large currents and high slew rates are two of the most important factors that enable an analog output circuit to accurately transmit the wide dynamic range of a music signal without degradation. The D-05X offers the ultimate performance as a line driver by adopting high-performance elements with a high current output and exceptionally fast slew rate (2,000V/µs) for excellent response speed. Two of these buffer circuits are employed per channel. By configuring them differentially to drive the XLR outputs and in parallel to drive the RCA outputs, the instantaneous output current available is maximized. By maximizing instantaneous current output, the D-05X reproduces the full dynamics of music with breathtaking realism.
"ES-LINK Analog" Method for High Quality Current Transmission
In addition to regular line connections (XLR and RCA), the D-05X features the new "ES-LINK Analog" transmission method developed by ESOTERIC. This is a current transmission signaling that utilizes the high performance of the HCLD buffer circuit and its enhanced ability to supply current at high-speed. This is the ideal analog audio transmission as it is free from impedance of signal route, thus fully maximizes the system's potential when connected to a compatible device.
Wide-Range D/D Conversion Compatible with Many Sources
In addition to playback at a source's original sampling frequency, the D-05X also features PCM up-conversion capability (2x, 4x, 8x) and PCM-to-DSD conversion that uses a proprietary algorithm to convert the PCM signal to fixed 22.5MHz DSD, enabling significantly smoother musical reproduction.
Digital Inputs Support High Sampling Rates
The D-05X's coaxial and optical inputs support PCM signals up to 24-bit/192kHz and 2.8MHz DSD (DoP). Two XLR inputs support 48-bit/192kHz (ES-LINK3), 24-bit/384kHz (Dual AES 8Fs) and 5.6MHz DSD (DoP Dual XLR mode).
USB Support for 22.5 MHz DSD, 768 kHz/32-bit PCM, and Asynchronous Transmission
The D-05X includes a USB terminal for connecting to computers, and the driver and "ESOTERIC HR Audio Player" playback software can be downloaded from the ESOTERIC website free-of-charge. The D-05X supports asynchronous transmission and playback at high sampling rates up to 22.5 MHz DSD and 768 KHz/32-bit PCM studio-master-quality source files.
Changeable XLR Output Pin Assignment
As phase can be digitally inverted in a contactless system, either Hot 2 or Hot 3 can be selected with no deterioration in sound quality.
