About the Grandioso C1X
The Esoteric Grandioso C1X is a two-chassis, solid-state flagship line preamplifier, hand-assembled in Tokyo, Japan. Its dual-mono, fully balanced architecture separates the audio control unit from its dedicated external power supply. Key design elements include Esoteric’s Ultra Fidelity Attenuator System with 1,120 volume steps in 0.1 dB increments, high-current HCLD output buffers, EDLC super-capacitor support at the output stage, and ES-Link Analog current-transmission connections for compatible Esoteric power amplifiers. It is an analog line-stage preamplifier: it has no phono stage, DAC, headphone output, network/streaming functions, Bluetooth, or digital audio inputs.
