A Legacy of Consummate Purity and Perfection.Esoteric’s new C-03Xs Preamplifier and S-03 Power Amplifier carry on the refinement of the 02 Series’ superb qualities of musical reproduction, which stand as a Grandioso legacy.Their minimalist approach to the consummate purity of sound returns to the very source of audio component design to give birth to a rich new range of musical experience. Hand-assembled one-by-one in Esoteric’s Tokyo factory, each unit combines the most advanced technologies with an unprecedented level of craftsmanship to give life to a preeminent philosophy of sound appreciation, from which a timeless new standard is born.At the heart of every fine system, it is the preamplifier that determines one’s ideal sound. Applying Esoteric’s wealth of knowledge and technology, the C-03Xs carries forward in continuous succession the Grandioso lineage of high fidelity and breathtaking powers of musical expression, drawing on the refined sensitivities of musicians and engineers alike to transcend the boundaries of sound reproduction quality.The preamplifier is a crucial component that determines the ‘sound’ of an audio system, and represents the passion and commitment of its makers. As the crowning achievement of the Esoteric Sound, the Grandioso C1 opened new horizons for ‘Made in Japan’ preamplifiers. Now, this expressive power gives birth to the next-generation C-02X; a stereo preamplifier created to transcend the concept of high fidelity and resonate with the refined sensibilities of engineers and musicians alike.
