Its fully discrete, fully balanced Class A MOSFET design delivers up to 10W into 32 Ω with low distortion and exceptional dynamics, effortlessly driving even the most demanding cans. \n\nPowerful Fully-Balanced Class-A Output\n\nThe PRELUDE’s magic lies in its fully-balanced Class-A MOSFET amplifier design, capable of delivering up to 10W into 32Ω and 560 mW into 600Ω. This high-current output ensures even the most power-hungry headphones are driven effortlessly, translating into confident dynamics and stable performance across genres.\n\nDiscrete Circuitry with Balanced Conversion\n\nRather than relying on integrated chips, the PRELUDE uses a fully-discrete analog signal path. It converts single‑ended RCA to balanced internally, maintaining the benefits of balanced architecture (lower noise and greater channel separation). The result is a clean, interference-free signal that stays faithful to the source.\n\nPrecision Control via ALPS Potentiometer\n\nThe front-panel volume knob houses an ALPS quad-balance potentiometer—an industrial-grade component known for its smooth and consistent adjustment. This precision ensures channel balance remains stable as you adjust volume, keeping stereo imaging intact across listening levels. \n\nClean Power from Toroidal Transformer\n\nInside the PRELUDE sits a custom high-power, low-noise toroidal transformer paired with a multi-channel regulator circuit. This power design supports the amplifier’s Class A operation and provides a clean rail to the headphone protection circuitry for reliable performance. \n\nRigid One-Piece Aluminum Chassis\n\nHoused in a solid aluminum shell, the PRELUDE benefits from both durability and acoustic cleanliness. The chassis design reduces mechanical resonance that can color sound, serving as","images":["https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-hifiman-goldenwave-prelude-desktop-class-a-headphone-amp-1176357869.webp?v=1751559764","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-hifiman-goldenwave-prelude-desktop-class-a-headphone-amp-1176357868.webp?v=1751559761","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-hifiman-goldenwave-prelude-desktop-class-a-headphone-amp-1176357865.webp?v=1751559654","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-hifiman-goldenwave-prelude-desktop-class-a-headphone-amp-1176357867.webp?v=1751559758","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-hifiman-goldenwave-prelude-desktop-class-a-headphone-amp-1176357866.webp?v=1751559656","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-hifiman-goldenwave-prelude-desktop-class-a-headphone-amp-1176357870.webp?v=1751559767"],"price":2499,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:25:57.426Z"},"share_url":"https://firestarter.network/l/lst_BoHvotJT","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
