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. \u003c\/span\u003e\u003c\/p\u003e\n \u003ch2\u003e\n \u003cstrong\u003ePowerful Fully-Balanced Class-A Output\u003c\/strong\u003e\u003cbr\u003e\n \u003c\/h2\u003e\n \u003cp\u003eThe 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.\u003cbr\u003e\u003c\/p\u003e\n \u003ch2\u003e\n \u003cstrong\u003eDiscrete Circuitry with Balanced Conversion\u003c\/strong\u003e\u003cbr\u003e\n \u003c\/h2\u003e\n \u003cp\u003eRather 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.\u003c\/p\u003e\n \u003ch2\u003e\n \u003cstrong\u003ePrecision Control via ALPS Potentiometer\u003c\/strong\u003e\u003cbr\u003e\n \u003c\/h2\u003e\n \u003cp\u003eThe front-panel volume knob houses an ALPS quad-balance potentiometer—an industrial-grade component known for its smooth and consistent adjustment.
