Stereo Power Amplifier
Grandioso C1X solo
It brings out the best in each piece of equipment that makes up the system, bringing an exceptional experience that eliminates the existence of the audio system in a pleasant sense of unity with the music, – It is the most important role of the preamplifier as the command center of the audio system.
The Grandioso C1X is the flagship model of ESOTERIC's flagship preamplifier, Grandioso, which bears the proud ESOTERIC trademark "Grandioso". The Grandioso C1X is a reference for the next generation, featuring a carefully designed dual balanced circuit, a complete dual mono configuration, a powerful buffer amplifier and power supply circuit to drive the power amplifiers, and ES-LINK Analog current transmission that challenges the limits of fidelity. It is a flagship preamplifier that incorporates all of ESOTERIC's wisdom and numerous technological innovations that could become the reference of the next generation.
The Grandioso C1X "solo" edition is housed in an integrated chassis without changing not only the internal circuit configuration of the original C1X, but also the five independent power transformer configurations for each circuit block, to achieve an elegant and beautiful size factor while maintaining the C1X's signature sound.

With the birth of the Grandioso M1X, the flagship monoblock power amplifier, the ESOTERIC amplifier design platform has been completely revamped. The Grandioso S1 has now been reborn as the Grandioso S1X, the flagship of a completely different class-A stereo power amplifier.
The monoblock M1X embodies ESOTERIC's idea of the ideal amplifier. The dynamic sound of the M1X, produced by a completely redesigned drive stage and a powerful power supply unit that incorporates an enormous amount of material, has captivated audiophiles around the world. The S1X, a Class-A stereo model, beautifully follows the M1X's signature sound of "a sense of dynamism that unleashes the full power of music" and "a sense of grand scale." In exchange for its high power of 2,400W/1 ohm, the S1X has gained a new half the space factor and the transparent and detailed expressiveness that only Class-A can deliver.
Here is a milestone model that realizes ESOTERIC's ideal of the Class-A stereo amplifier.
Newly designed drive stage with 5-parallel push-pull drive by high-capacity bipolar transistors
Pure Class-A operating range of 50 W/8 ohm provides a dense musical expression that combines precision and dynamism
“ES-LINK Analog" transmission pushes the limits of fidelity between Pre/Power amplifiers
Superior power linearity for unparalleled dynamics (50W/8Ω to 100W/4Ω)
Large-capacity toroidal-core power transformer with extremely responsive to dynamic current supply changes
3-transformer configuration with independent power transformers for the front stage, drive stage, and control system
The design goal of Esotericis to recreate the original master sound. ESOTERIC is a high end audio manufacturer established in 1987. Based in Tokyo, all products (ranging from network audio players, SACD players, DACs to amplifiers) are hand built in our factory to exacting standards. Cutting edge technologies, engineering excellence, state-of-the-art Japanese craftsmanship and passion for innovation －all coming together to unveil new dimensions in musical experience.
