Esoteric S-02 power amplifier. The unique feeling of space that occurs only when the sound is flowing freely and widely, as well as the impression of a truly live performance of music, occurs only when the amplifier has a generous supply of power for proper control of acoustic systems. To meet these requirements, Esoteric amplifiers use only the very best components and massive power supplies.
The Esoteric Grandioso S1X is the flagship in the perfect class of Class A stereo power amplifiers. The Esoteric Grandioso S1X is a Class A stereo amplifier that perfectly repeats the signature sound of the M1X monoblock: "a sense of dynamism that reveals the full power of music" and "a sense of grand scale." In exchange for the pure power of 50 watts/8 ohms Class-A), the S1X offers a half-size form factor and the transparent and detailed expressiveness that only Class A can provide. This is an iconic model that embodies Esoteric's ideals in the field of Class A stereo amplifiers.
