I-03 Stereo Integrated Class “D” Power Amplifier

SKU: I-03 Category:


Sensuous French Impressionism and spirit of German Classicism. Cool West Coast jazz and hot East Coast jazz. Dynamism of black contemporary and sophistication of Eurobeat.

The unique characteristics of sound and flavor of music that were cut in the original master recordings are passed on to the listeners without any trimming of parts. Esoteric is committed to new developments in order to fully apply the Esoteric-original Master Sound Works concept to the
integrated amplifier.
Ingenuity that breaks from conventional concepts and use of materials without cost constraints. Esoteric has consolidated audio technologies it has fostered over years of developing separate types of amplifiers and has without compromise, applied them into creating an integral type amplifier. The result has been the birth of Esoteric’s flagship integrated amplifier I-03.

When you look at the simple body form that eliminates all excessive features, you can discover the passions of our engineers in their devotion to developing new high-end models and the flavor of reproducing music in its original form.
