The Stereo 20 PP is a compact integrated amplifier inspired by a classic 1955 design — „small but perfect”. In an ultra-linear push-pull configuration on EL84 valves it offers around 13 W per channel with a delicate, airy and effortless sound, ideal for smaller rooms and efficient loudspeakers.
The fully triode input stage is based on ECC83/ECC82 valves. Minimal negative feedback means the amplifier works superbly with both CD players and modern sources — DACs or streamers. A dedicated output-transformer winding feeds a high-quality headphone output.
Despite its accessible price, it is a genuine audiophile design: full hand-wired point-to-point assembly, Solen capacitors, silver-plated PTFE wiring and gold-plated input and speaker terminals. A valve cage and a comprehensive manual are included. A triode version is also available — at no extra cost.
