All instruments start to breathe naturally and dynamically on an inky black background of silence. A gem of preamplifier created by the wisdom of Esoteric. 

The most important role of the preamplifier is to act as the command center of the audio system, drawing out the performance of each device that makes up the system to the highest level, and providing the listener with an exceptional listening experience that makes them forget the existence of the audio system.

The C1X is the flagship model of Esoteric’s preamplifiers. It bears the proud Esoteric trademark “Grandioso”. The Grandioso C1X is a reference standard for the next generation, featuring a carefully designed dual-balanced circuit, a complete dual mono configuration, a powerful buffer amplifier, and a 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.

The Grandioso C1X “solo” edition is housed in an integrated chassis without changing the internal circuit configuration of the original C1X, as well as its five independent power transformer configurations for each circuit block, achieving an elegant and beautiful size form factor while maintaining the C1X’s signature sound.
