It produces \u003cstrong\u003e145 watts RMS per channel into 8 ohms\u003c\/strong\u003e and demonstrates high stability with challenging, low-impedance loads, capable of handling 2-ohm loads effectively. The circuit topology relies on a fully complementary design, utilizing 12 Hitachi MOSFET power devices (six per channel) to deliver high-current, authoritative bass and a wide, stable soundstage.\u003c\/p\u003e\n\u003cp\u003eThe proprietary Excelinear adjustment, helps reduce total harmonic distortion to below 0.007% at 1 watt.\u003cspan class=\"Apple-converted-space\"\u003e  \u003c\/span\u003eInternally, the XL-280 deviates from conventional transistor amplifiers by eliminating Zobel networks at the speaker output, relying on its inherent stability to handle reactive loads without oscillation. The amp’s heavy-duty construction and high-quality components, including polypropylene capacitors, metal film resistors, and heavy-duty power filtering caps all contribute toward impressive power, with poise.\u003cspan class=\"Apple-converted-space\"\u003e \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eThis piece has been thoroughly reviewed by our in-house tech with a clean bill of health.  It plays clean and delivers on the marketing hype.
