Monoblock D/A Converter

Grandioso D1X SE

The Grandioso D1X SE is ESOTERIC’s flagship monoblock DAC, engineered to deliver exceptional digital-to-analog conversion through proprietary discrete circuitry, advanced clock technology, and meticulous power supply design.

Master Sound Discrete DAC

Featuring ESOTERIC’s fully in-house-designed DAC architecture, the D1X SE employs proprietary FPGA processing at 64-bit/512Fs without conventional DAC ICs, delivering highly detailed musical reproduction and dynamic expression.

Enhanced Analog Circuitry

The SE edition features carefully selected and upgraded analog components, including the IDM-01 amplifier module, refined filter components, and an optimized signal path for improved dynamics, natural textures, and lifelike musical presentation.

Master Sound Discrete Clock

The proprietary Master Sound Discrete Clock for Digital Player enhances clock precision and stability. Compatibility with an external 10 MHz master clock generator allows further system synchronization.

Dual-Mono Architecture

Separate left- and right-channel units, independent digital and analog power supplies, and large toroidal transformers help minimize interference and provide optimized operating conditions for each channel.

ESOTERIC-HCLD & ES-LINK Analog

The high-current output buffer and proprietary ES-LINK Analog transmission system support fast, powerful signal delivery when connected to compatible amplification equipment.

High-Resolution Audio Support

Supporting DSD up to 22.5 MHz and PCM up to 768 kHz/32-bit, the D1X SE also offers selectable PCM upconversion and PCM-to-DSD conversion for flexible digital playback.

Precision Chassis Engineering

A multilayer chassis, newly designed Pinpoint feet, and a semi-floating top panel help control vibration and mechanical stress, reflecting ESOTERIC’s uncompromising approach to high-end audio engineering.
