Great Pioneer SA-9800 Integrated Amplifier

ABOUT:

The Pioneer SA-9800 is one of the most celebrated amplifiers of the golden hi-fi era — a statement of Japanese engineering perfection.

Equipped with Pioneer’s exclusive Non-Switching Amplifier (NSA) circuit, it combines the warmth of Class A with the power efficiency of Class AB, delivering ultra-low distortion and natural musical flow.

Every element — from the heavy brushed aluminum faceplate to the blue-lit VU meters and precision tone controls — exudes craftsmanship.

Renowned for its exceptional transparency, grip, and dynamic authority, the SA-9800 remains a collector’s choice for those who demand both performance and beauty.
