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.

    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.
