Esoteric Grandioso M1X Reference Class A/B Monoblock Power Amplifier (each)

Esoteric Grandioso M1X Is a New Milestone in Amplifier Innovation

Esoteric Grandioso M1X is a flagship monaural power amplifier that embodies both the wisdom of high-end audio tradition and the precision of advanced engineering. Designed as the successor to the original Grandioso M1, the M1X raises the benchmark for power delivery, musical expression, and acoustic fidelity, creating an amplifier that transforms silence into soundscapes of breathtaking scale and intimacy.

Esoteric Grandioso M1X Creates a Dynamic Soundscape

Esoteric Grandioso M1X is engineered to disappear behind the music, leaving only the full scope of performance. A completely redesigned drive stage and a newly developed power supply unlock a signature sound with heightened dynamism and dimension. Orchestral crescendos swell with authority, while delicate chamber works retain a lifelike immediacy, all free from the veil of distortion or coloration.

Esoteric Grandioso M1X Delivers Ultimate Fidelity

Esoteric Grandioso M1X incorporates ES-Link Analog, the company’s proprietary current transmission system, to achieve flawless preamp-to-amplifier communication. Unlike conventional voltage transmission, ES-Link Analog sends 100 times more current, making the signal far less susceptible to interference and ensuring that the musical energy reaches the amplifier unaltered. The transmission is unaffected by cable impedance, preserving complete integrity from source to output and pairing seamlessly with the Grandioso C1X linestage preamplifier.

Esoteric Grandioso M1X Provides 2,400W/1Ω Linear Power

Esoteric Grandioso M1X achieves astonishing drive capability with its expanded 12-parallel output stage, scaling 150% larger than its predecessor. The amplifier maintains linear power from 300W at 8Ω up to 2,400W at 1Ω for music signals, providing ample current to control even the most demanding loudspeakers. This ensures unrestricted compatibility with a wide spectrum of reference-grade speakers while maintaining tonal purity across the full dynamic range.

Esoteric Grandioso M1X Harnesses Infinite Power

Esoteric Grandioso M1X houses the largest power supply ever built by the company, occupying 60% of the chassis interior. At its core lies a 3,000VA transformer weighing 19kg, wound with heavy-gauge conductors for superior rectification. Supporting this powerhouse are custom-built capacitors with a combined capacity of 60,000μF, ensuring effortless current delivery and refining the amplifier’s tonal depth and natural warmth.

Esoteric Grandioso M1X Enhances Resolution

Esoteric Grandioso M1X integrates a dedicated power supply exclusively for the pre-drive voltage amplification stage. By isolating this section from the current-hungry drive stage, the amplifier secures extraordinary resolution and micro-detail retrieval. Even during dense orchestral peaks, the M1X extracts subtle instrumental textures, capturing the expressive nuance of each performance.

Esoteric Grandioso M1X Sustains Harmonics

Esoteric Grandioso M1X follows an “aesthetics of subtraction” philosophy, keeping circuitry intentionally minimalist to preserve the natural harmonic overtones of music. Its 24 drive transistors are thermally balanced for absolute stability, while a single-pole phase compensation circuit allows for a coil-less output stage. This restraint enables the amplifier to project harmonics with richness and authenticity, drawing out the tonal character often lost in complex circuitry.

Esoteric Grandioso M1X Controls Deep Frequency Authority

Esoteric Grandioso M1X utilises oversized copper-clad circuit boards, massive bus bars, and ultra-thick cabling with bolted connections that evoke the engineering of aircraft engines. This robust construction reduces internal impedance, allowing the amplifier to grip even large woofers with commanding authority. The result is bass reproduction that extends to the deepest registers while maintaining absolute control and definition.

Esoteric Grandioso M1X Shapes Sonic Gradation

Esoteric Grandioso M1X excels not only in explosive power but also in subtle gradations between silence and sound. Its newly designed balanced input stage provides noiseless transmission into the amplification chain, while high-spec components such as IDM-01 discrete amplifier modules and FET switches elevate signal purity. This meticulous design enables the amplifier to convey fine microdynamics, revealing textures and layers with lifelike realism.

Esoteric Grandioso M1X Demonstrates Mechanical Perfection

Esoteric Grandioso M1X achieves vibration control through mechanical engineering on par with Formula One chassis design. The rigid yet flexible aluminium structure balances strength with controlled resonance. A 35mm-thick aluminium front panel ensures solidity, while the semi-floating top panel fosters openness of tone. Specially engineered isolation feet further dissipate mechanical stress, securing acoustic stability.

Esoteric Grandioso M1X Features a Dual Honeycomb Grille

Esoteric Grandioso M1X showcases a striking Dual Honeycomb Grille on its top panel. This signature design evolution from the M1 not only enhances visual presence but also maximises thermal efficiency by optimising airflow. By layering two offset honeycomb sheets of varying thickness, vibrations are dispersed with precision, yielding a purer and more open sound signature.
