【Dual MA12070 Chips for Balanced Performance】
Each channel of the TOPPING PA3S uses its own MA12070 Class D amplifier chip, reducing crosstalk, improving heat distribution, and enhancing long-term reliability.
【High Output Power for Demanding Speakers】
Delivers 80W x2 @ 4Ω (10% THD+N) or 65W x2 @ 4Ω (1% THD+N), offering enough power to drive most bookshelf and even some floor-standing speakers with clarity and headroom.
【Balanced TRS and RCA Inputs】
Supports both TRS balanced and RCA single-ended inputs; front-panel input switching with memory function avoids ground loop noise and ensures clean, hum-free playback.
【Low Distortion in Real Listening Range】
Achieves its lowest THD+N in the 10–20W range—right where most everyday listening happens—offering natural and clean audio during normal use.
【Versatile Pairing with DACs】
Combine the TOPPING PA3S with an external DAC to expand input options or with a DAC+HPA stack for a fully integrated digital, headphone, and speaker system.
【Compact, Efficient, and Reliable】
Designed for modern HiFi setups, the TOPPING PA3S provides high efficiency and low heat in a compact form, making it ideal for desktops and home stereo environments.
