PA-10 EVO

GoldNote PA-10 Evo — stereo power amplifier. Compact stereo or mono power amplifier delivering 140W per channel at 8Ω stereo or 280W mono, with selectable high (250) or low (25) damping factor. Balanced XLR and unbalanced RCA inputs with GN Link master-slave ON/OFF control. Slim 200×80×260mm chassis weighing just 3kg; compatible with DS-10 Evo and IS-10.

Technical background

GoldNote power amplifiers use proprietary Optical BIAS control — monitoring output transistor bias continuously via infrared sensors rather than mechanical trimmers — for drift-free long-term stability across all operating temperatures. Selectable damping factor (250 or 25) adapts bass control to different speaker types. The P-1000 mkII preamplifier adds three independent linear power supplies filtered by military-derived noise-cancelling coils, and a 100-step ALPS optical encoder volume control with 0.5dB resolution.

Design story

GoldNote's amplifier development has always prioritised long-term real-world stability. The Optical BIAS system — developed after observing that conventional bias trimmers drift with temperature and age — continuously corrects output transistor operating point using infrared sensors. The P-1000 mkII chassis is machined from a single aluminium billet, with three fully independent power supplies filtered by coils derived from helicopter avionics noise-cancellation technology, making it the most mechanically and electrically isolated preamplifier in the GoldNote range.
