Esoteric Grandioso C1X Reference Pre-amplifier

Grandioso C1X Reference Preamplifier Defines Flagship Performance

Grandioso C1X Reference Preamplifier is Esoteric’s dual-chassis flagship model, combining a control unit and a separate 29kg power supply to achieve unmatched clarity and authority. Designed as the successor to the award-winning Grandioso C1, the C1X reimagines preamplification with new technologies that elevate precision, transparency and musical realism.

Grandioso C1X Reference Preamplifier Delivers Ultra Fidelity Volume Control

Grandioso C1X Reference Preamplifier introduces Esoteric’s Ultra Fidelity Attenuator System, built around the proprietary UFA-1792 module. With 1,120 steps in ultra-fine 0.1dB intervals, it surpasses conventional attenuators, combining the sonic purity of fixed resistance circuits with the smooth operation of variable resistance systems. This breakthrough gives audiophiles absolute control with no compromise in tonal balance.

Grandioso C1X Reference Preamplifier Employs Discrete Modular Amplification

Grandioso C1X Reference Preamplifier incorporates Esoteric’s IDM-01 Integrated Discrete Amplifier Module, delivering dynamic yet delicate sound. Parallel HCLD buffer amplifiers powerfully drive ES-LINK Analog and XLR outputs with a remarkable slew rate of 2,000V/μs, ensuring effortless system expansion to bi-amp or multi-amp setups while preserving musical integrity.

Grandioso C1X Reference Preamplifier Harnesses EDLC Super Capacitors

Grandioso C1X Reference Preamplifier achieves explosive energy and stability through EDLC Super Capacitors providing 250,000,000μF per channel. This enormous storage capacity enhances low-frequency control, ensuring bass reproduction is deep, articulate and realistic, while preserving the microdynamics of delicate recordings.

Grandioso C1X Reference Preamplifier Features Fully Balanced Dual-Mono Design

Grandioso C1X Reference Preamplifier employs a true dual-mono architecture, with independent left and right signal paths from input to output. Balanced HOT and COLD circuitry minimises noise and crosstalk, while ES-LINK Analog transmission delivers current up to 100 times greater than conventional voltage-based systems, ensuring a purer connection when paired with Grandioso digital sources.

Grandioso C1X Reference Preamplifier Combines Precision Engineering with Luxury Craft

Grandioso C1X Reference Preamplifier showcases Esoteric’s hallmark craftsmanship, with billet aluminium knobs mounted on precision bearings and a dual-faced aluminium remote for intuitive control. Additional functions include input gain adjustment, channel balance, AV THRU mode, RS-232C control, and trigger connectivity, ensuring versatility in complex systems.
