About the PA5

The Nakamichi PA-5 STASIS is a vintage solid-state power amplifier manufactured in 1987-1990 that represents a refined approach to audio amplification. Featuring the acclaimed STASIS circuit architecture designed by Nelson Pass, this amplifier delivers 100 watts per channel into 8 ohms with exceptional clarity and musicality. The PA-5 is the smaller sibling to the more powerful PA-7 model (200W per channel) and is capable of driving 90% of speaker types with ease. Known for its big, beautiful musical sound with minimal listening fatigue, the amplifier features a minimalist design philosophy with just a power on/off button and no tone controls, allowing the preamp to handle all sound shaping. The unit runs warm due to its high idling current consumption but includes clipping indicators and can actually deliver approximately 140-150 watts into 8 ohms before clipping, exceeding its rated specifications. Built with meticulous attention to detail and quality component selection, the PA-5 is renowned for coherent imaging, excellent speaker load compatibility, and reliable long-term performance. Original MSRP was $1,650.
