Power is supplied by an oversized, in-house manufactured toroidal transformer feeding a large bulk storage capacitor bank, an arrangement that holds the rails steady when the music demands sustained current rather than brief peaks.\u003c\/p\u003e\n\u003cp\u003eA damping factor of 350 at 1 kHz into 8 ohms indicates tight control over woofer motion, which is heard as defined rather than loose bass. Balanced XLR and unbalanced RCA inputs are provided, along with dual 5-way binding posts per channel for bi-wiring. The aluminium chassis carries a front-panel display with selectable meter views to match the rest of the Michi Prestige range.\u003c\/p\u003e\n\u003ch3 style=\"color: #0f527f;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e390 watts per channel Class AB into 4 ohms\u003c\/li\u003e\n\u003cli\u003eOversized in-house manufactured toroidal transformer\u003c\/li\u003e\n\u003cli\u003eHigh-efficiency bulk storage capacitor bank\u003c\/li\u003e\n\u003cli\u003eDamping factor of 350 for firm bass control\u003c\/li\u003e\n\u003cli\u003eBalanced XLR and unbalanced RCA inputs\u003c\/li\u003e\n\u003cli\u003eDual 5-way speaker binding posts for bi-wiring\u003c\/li\u003e\n\u003cli\u003eFront-panel display with selectable meter views\u003c\/li\u003e\n\u003cli\u003eSignal to noise ratio above 115 dB\u003c\/li\u003e\n\u003cli\u003eStable into loads down to 4 ohms\u003c\/li\u003e\n\u003cli\u003eSupplied with a dedicated remote control\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 style=\"color: #0f527f;\"\u003eWarranty\u003c\/h3\u003e\n\u003cp\u003eThis product comes with a 2-year manufacturer warranty.\u003c\/p\u003e\n\u003ch3 style=\"color: #0f527f;\"\u003eWhy Consider the Michi Prestige S430\u003c\/h3\u003e\n\u003cp\u003eA dedicated power amplifier is the usual next step once a system outgrows an integrated. The S430 gives the output stage an entire chassis, its own transformer and unshared supply rails, and no preamplifier circuitry alongside it. The practical benefit shows up on loudspeakers that dip toward 4 ohms in the bass, where the 390 watt rating and 350 damping factor keep the low end controlled at levels that would compress a lesser amplifier.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIdeal For\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePairing with the Michi Prestige P430 preamplifier\u003c\/li\u003e\n\u003cli\u003eLarge rooms and demanding 4-ohm floorstanding loudspeakers\u003c\/li\u003e\n\u003cli\u003eSystems upgrading from an integrated amplifier to separates\u003c\/li\u003e\n\u003cli\u003eBi-wired loudspeaker installations using dual binding posts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 style=\"color: #0f527f;\"\u003eWhat's in the Box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMichi Prestige S430 Stereo Power Amplifier\u003c\/li\u003e\n\u003cli\u003eRemote control\u003c\/li\u003e\n\u003cli\u003ePower cable\u003c\/li\u003e\n\u003cli\u003eOwner's manual\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 style=\"color: #0f527f;\"\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv class=\"ph-spec-wrap\"\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr class=\"ph-sec-hd\"\u003e\n\u003ctd colspan=\"2\"\u003eAmplifier Performance\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-label=\"Power Output (FTC)\"\u003ePower Output (FTC)\u003c\/td\u003e\n\u003ctd data-label=\"Value\"\u003e250 W per channel, 8 ohms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-label=\"Continuous Power Output\"\u003eContinuous Power Output\u003c\/td\u003e\n\u003ctd data-label=\"Value\"\u003e230 W per channel, 8 ohms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-label=\"Maximum Power Output\"\u003eMaximum Power Output\u003c\/td\u003e\n\u003ctd data-label=\"Value\"\u003e390 W per channel, 4 ohms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-label=\"THD\"\u003eTotal Harmonic Distortion\u003c\/td\u003e\n\u003ctd data-label=\"Value\"\u003eLess than 0.03%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-label=\"IMD\"\u003eIntermodulation Distortion\u003c\/td\u003e\n\u003ctd data-label=\"Value\"\u003eLess than 0.03% (60 Hz:7 kHz, 4:1)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-label=\"Frequency Response\"\u003eFrequency Response\u003c\/td\u003e\n\u003ctd data-label=\"Value\"\u003e10 Hz -
