Now Available on Apos Audio: TOPPING PA3s Fully Balanced Class D Amplifier

Fully Balanced + Class D

Apos Audio now carries the TOPPING PA3s Fully Balanced Class D Amplifier. With 80W x2 @4Ω of power, the PA3s is a powerful yet simple amplifier that will suit your passive speaker needs.

As a balanced amplifier, it powers each incoming channel with a separate amplifier chip. As a Class D amp, it uses far less power than Class A amps, making it super efficient. We think it’s a terrific option if you want a powerful, efficient amplification option for your bookshelf, desktop, or floor stand speakers.
