Esoteric Grandioso D1X SE Monoblock D/A Converter
Best ultimate fidelity for discerning audiophiles.
The Esoteric Grandioso D1X SE Monoblock D/A Converter represents the pinnacle of digital-to-analog conversion, designed to faithfully reproduce the full dynamics and energy of original master recordings. It features a groundbreaking Master Sound Discrete DAC with high 64-bit/512Fs resolution, supporting up to 22.5MHz DSD and 768kHz PCM audio. Esoteric's proprietary FPGA algorithm and a discrete circuit design, eschewing generic DAC ICs, ensure unparalleled sonic purity. The luxurious build includes four DAC circuits per channel, each with an independent power supply, and utilizes ultra-high precision resistors for accurate processing. The SE model further refines the analog circuitry with the Integrated Discrete-Amplifier Module IDM-01 for enhanced vibrancy and subtle amplification.

Know before you buy
Unlike generic DAC chips, the Master Sound Discrete DAC uses a proprietary FPGA algorithm and high-precision resistors. This discrete design allows for greater control over the signal path, resulting in higher resolution and a more faithful reproduction of the original master recording.
Yes, for the highest level of signal integrity, we recommend using the ES-Link5 digital transmission for digital sources and ES-Link Analog for current-mode signal transmission between compatible components. These proprietary connections minimize signal loss and interference compared to standard cables.
By housing each channel in its own independent chassis with dedicated power supplies, the D1X SE eliminates electrical and magnetic interference between channels. This configuration ensures superior channel separation and a more expansive, precise soundstage.
The D1X SE is highly versatile and supports a wide range of high-resolution formats, including PCM up to 768kHz/32bit and DSD up to 22.5MHz. It is compatible with virtually all modern high-fidelity digital audio sources.
The Integrated Discrete-Amplifier Module (IDM-01) is an upgraded analog circuit component designed to enhance the vibrancy and musicality of the output. It provides subtle, refined amplification that improves the overall texture and realism of the analog signal.
While the D1X SE features high-precision internal clocking, it includes a 10MHz BNC clock input per channel. Adding an external master clock can further reduce jitter and improve timing accuracy for those seeking the absolute peak of digital performance.
