SKU: fac-Esoteric D-05X Category: Tags: ,


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. 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.

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.

*HCLD=High Current Line Driver

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.*

*A standard balance cable (with an XLR terminal) is used for connections, but the “ES-LINK Analog” method can only be used with compatible devices since it is a proprietary transmission method.

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).
