I evaluate all vintage audio brands, specializing in high-value manufacturers like Marantz, McIntosh, Pioneer, Technics, Bang & Olufsen, Thorens, and Revox. My expertise extends to Dutch heritage brands (Philips), German engineering (Braun, Telefunken), and Japanese precision audio (Yamaha, Sansui, Luxman). Whether you have common consumer equipment or rare audiophile pieces, I provide accurate market valuations based on current collector demand and international pricing databases.
