Developed as the natural companion to the Grandioso T1 turntable, the E1 introduces ESOTERIC’s unique \u003cstrong\u003eMC Balanced Current Input\u003c\/strong\u003e, dedicated optical-cartridge support, fully balanced dual-mono amplification, advanced equalization control, and a separate power-supply chassis.\u003c\/p\u003e\n\u003cp\u003eIts goal is simple but ambitious: extract more musical energy, lower noise, and greater realism from vinyl playback while offering the flexibility required by serious analog systems.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/www.esoteric.jp\/images\/products\/_esoteric\/e1\/e1_angled_image.jpg\" alt=\"E1\"\u003e\u003c\/p\u003e\n\u003ch3\u003eMC Balanced Current Input\u003c\/h3\u003e\n\u003cp\u003eThe Grandioso E1 includes \u003cstrong\u003ethree balanced XLR inputs specifically designed for moving-coil cartridges\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eInstead of converting the cartridge’s output current into a very small voltage through a conventional load resistor, the E1 accepts the MC cartridge signal directly as current.
