Maintained! AccuPhase 70's vintage stereo power amplifier is now in stock. A/B class switching and a completely independent left and right power transformer are used to suppress mutual interference and achieve clean sound. Like the Accuphase from the 70s, it combines cleanliness and strength, and it is also a sound maker leading to the P-500 reference power amplifier that followed. Dullness, there are threads (Daiki Goto)
