It uses a pure Class A\/B design and delivers 450 watts per channel into 8 ohms, 600 watts per channel into 4 ohms, and 1000 watts bridged into 8 ohms. Adcom positions it as an upgraded version of an already well-regarded amplifier platform, with careful attention paid to component selection throughout the design.\u003c\/p\u003e\n\n\u003ch3\u003eWhy We Like It\u003c\/h3\u003e\n\u003cp\u003eFor systems that demand grip, current delivery, and headroom, the GFA-585se stands out as a serious power amplifier. Its combination of high output, wide bandwidth, and very high damping factor makes it a strong match for demanding loudspeakers and listeners who want authority without giving up control.\u003c\/p\u003e\n\n\u003ch3\u003eKey Highlights\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003ePure Class A\/B stereo power amplifier\u003c\/li\u003e\n  \u003cli\u003e450 watts per channel into 8 ohms\u003c\/li\u003e\n  \u003cli\u003e600 watts per channel into 4 ohms\u003c\/li\u003e\n  \u003cli\u003e1000 watts into 8 ohms in bridged mode\u003c\/li\u003e\n  \u003cli\u003eFrequency response of +0, -0.25 dB from 10Hz to 20kHz at 1 watt into 8 ohms\u003c\/li\u003e\n  \u003cli\u003ePower bandwidth of 20Hz to 20kHz\u003c\/li\u003e\n  \u003cli\u003eHigh damping factor of \u0026gt;800 from 20Hz to 20kHz\u003c\/li\u003e\n  \u003cli\u003e120VAC and 230VAC \/ 50-60Hz operation listed by manufacturer\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSystem Matching\u003c\/h3\u003e\n\u003cp\u003eThe GFA-585se is a natural fit for audiophiles building a high-current stereo rig, upgrading from an AV receiver, or pairing a dedicated preamp with a more capable amplifier stage. Its power reserves and bridged capability also make it attractive for systems using more demanding speakers.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable style=\"width:100%;
