The Heart of the System That Gives Life to Sound
Newly developed as a modular unit that can be used in both output and input amplifiers, Esoteric’s new IDM-01 Integrated Discrete Amplifier Module combines the advantages of a discrete configuration, which permits free selection of the individual parts that make up the circuit, and a modular form that can be assembled into a circuit having the smallest footprint possible. This new amplifier module will soon take its place as the heart of all future Esoteric amplifiers, delivering a dynamic yet delicate Esoteric sound.
Two-Chassis Amplifier and Power Supply Configuration
To achieve both the Grandioso C1X’s transparent sound field and its overall sense of dynamism, a separate two-chassis structure was selected as a means of physically separating the amplifier section from its power supply. The linear power supply unit is installed in a separate housing that weighs fully 29kg. This enables astoundingly clean amplification as the C1X transmits the full energy and dynamism of music to the power amplifiers while providing effortless control over the entire system.
Monoblock Configuration with Advanced Vibration Control
The Grandioso C1X’s Monoblock configuration ensures that left and right audio channels maintain total independence by design. These totally separate audio channels extend from the preamplifier inputs through the amplification section, and even to its separate DC power supply unit with its dual AC power cables. In fact, the C1X’s Monoblock structure effectively integrates two separate monaural preamplifiers into a single set of components that can suitably be referred to an Esoteric’s flagship.

From its dual AC inputs to its dual DC outputs, the power supply unit’s DC power supply features totally independent two-channel construction. In addition to these separate left and right channel input/output amplifier sections, the control unit features a total of five large power transformers together with high-capacity block capacitors, Schottky barrier diodes, and other carefully selected parts in keeping with this flagship model. Moreover, to accentuate the Grandioso series’ spacious sound, all internal circuit boards and even the units’ top plates feature a semi-floating design, while input and output circuit boards are effectively surface-mounted directly to the chassis.
The separate power supply features multi-layer chassis construction, with circuit boards and transformers mounted on separate chassis. By mounting these components on different chassis, transformer vibration is not only greatly reduced, it is also not transmitted to the circuit boards. Additionally, the bottom chassis features high-precision laser-cut slits for the transformer mounts. These slits effectively control vibration and direct it outward through Esoteric’s patented pinpoint feet.
Satisfying Operation with a Consummate Feeling of Quality
The C1X’s prominent volume control and input selector knobs are machined from high-grade billet aluminum, while their bearing systems, originally developed for the VRDS drive’s spindle shaft mechanism, ensure precise rotation with no core deviation. Fine-tuned adjustment ensures optimal rotational torque for a smooth, analog-like operating feel in keeping with Esoteric’s premier flagship preamplifier.
New Double-Faced Remote Controller Design
The Grandioso C1X’s compact new remote controller is also designed to operate other Esoteric digital source devices. Its simplified functional design features buttons positioned on both sides of the unit for easy use in all scenes of operation. Highly advanced metal processing ensures that the unit’s smartphone-sized aluminum case fits comfortably in your hand, while Esoteric’s innovative approach to design allows you to experience well-thought-out operability and exceptional craftsmanship every time you pick up the remote controller.
