Esoteric Grandioso C1X Linestage Preamplifier – Made in Japan

$49,500.00 inc. GST

Category: Brand:


When designing the Esoteric Grandioso C1X the Esoteric engineers looked ahead to what lies beyond what a preamplifier should be. In order to surpass the legendary Grandioso C1, winner of countless awards following its 2014 introduction, the company set out to thoroughly reimagine the volume control system – often considered to be the fundamental core of a preamplifier – thereby dramatically improving its precision and clarity of sound to become the standard for a new era. Esoteric’s accumulated engineering knowledge and expertise was focused on the creation of a new preamplifier that meets the desires of the consummate audiophile.
