Pioneer SX-580 Vintage Receiver | 20 WPC | Cherry Wood Finish

Pioneer SX‑580 Vintage Receiver – Serviced, 20 WPC, Custom Ottawa Valley Cherry Wood Cabinetry

The Pioneer SX‑580 you see here isn’t just a compact receiver—it’s a beautifully restored icon of late‑1970s hi‑fi.
Lovingly serviced and detailed by Radique Audio, this circa‑1979 classic delivers 20 watts per channel of clean, musical Pioneer sound with our exclusive custom Ottawa Valley cherry wood cabinetry, precision‑applied for a warm, elegant finish that’s unmistakably Radique.

Compact and refined, the SX‑580 was designed at the tail end of the receiver wars—bringing big Pioneer performance to smaller spaces. Built in Japan during the golden age of silver‑faced audio, it features robust construction, clean controls, and that signature Pioneer glow from its illuminated dial and stereo meters.
