Excellent Performance With Dual Independent Amplifier Chips:-

Topping PA3S adopts one MA12070 class D amplifier chip for each channel. It provides high-quality performance with reduced crosstalk. A separate amplifier chip for each channel also reduces the load on each chip, effectively improving reliability and extending the lifespan of the chipset. Just by including the PA3S in your chain, you will notice drastic improvements with your speaker system.

Powerful Output For Powerful Performance:-

Topping PA3S achieved an output power rating of up to 80Wx2 @ 4Ω with THD+N at 10%. In high-quality THD+N 1%, the PA3S churns out 65Wx2 @4Ω. It is more than adequate to power up bookshelf speakers and even some full-size floor speakers. Topping PA3S can bring life to your Bookshelf speakers with its powerful performance.

Balanced & Single-Ended Input Architecture:-

Users can feed the audio signal to the PA3S using both single-ended RCA and Balanced TRS connections. The use of balanced input eliminates potential ground loop problems resulting in a cleaner, noise-free background. Users can easily switch between both the input options using the button on the front.

Compact & Elegant:-

Topping PA3S has a compact form factor, the amp has elegant looks with a rich, smooth finish on the aluminum chassis. The volume wheel is smooth and allows for precise volume adjustment with the speakers. Its form factor makes it an easy companion that can be placed anywhere on the desk.
