The Grandioso S1 has now been reborn as the Grandioso S1X, the new flagship in a completely different class of Class-A stereo power amplifiers.\u003cbr\u003eThe monoblock M1X embodies Esoteric’s idea of the ideal amplifier. The dynamic sound of the M1X, produced by a completely redesigned drive stage and a powerful power supply unit that incorporates an enormous amount of material, has captivated audiophiles around the world. The S1X, a Class-A stereo model, beautifully follows the M1X’s signature sound of “a sense of dynamism that unleashes the full power of music” and “a sense of grand scale.” In exchange for its high power of 2,400W\/1 ohm, the S1X offers a half the space form factor and the transparent and detailed expressiveness that only Class-A can deliver.\u003cbr\u003eHere, is a milestone model that realizes Esoteric’s ideals of the Class-A stereo amplifier.\u003cbr\u003e \u003c\/p\u003e\n\u003c\/div\u003e\n\u003cfigure class=\"col-sm-7\"\u003e\u003cimg alt=\"Grandioso S1X\" class=\"img-responsive\"
