TOPPING PA3s
Fully Balanced Architecture
PA3s features MA12070 Class D power amplifier chips to allow separation in layout, improving performance and reducing crosstalk. The power is shared across two chips, and the heat dissipation is also halved for each chip, improving reliability and extending the lifespan of the product.
Powerful Output for Your Speakers
The Topping PA3s has the capacity to drive any bookshelf speakers and even some floor speakers, because it can output 80W x2 at 4ohm load, 10%THD+N. Especially, in higher standard of THD+N of 1%, output power will be 65Wx2 at 4ohm load.
TRS Balanced & Single-Ended Inputs
Topping PA3s specializes in TRS balanced input and RCA single-ended input. These two inputs are selectable at the front panel button. When it was turned off, PA3s will remember the input selected. To sum up, both inputs eliminate potential ground loop problems giving the pristinely clean audio without any hum.
Splendid Ultra-Low Distortion
PA3s enables the lowest THD+N to be achieved in the range of 10-20W output, which happens to be the power range commonly used for listening to music. If you seek a powerful power AMP for your HiFi speakers, PA3s will serve you excellently with its true high-resolution performance.
Best Match with D10
D10 Balanced and the E50 are recently launched by Topping, both of which can provide high-fidelity USB decoding and TRS balanced output. When used with PA3s, it is equivalent to adding a high-performance USB input to PA3s, and the function is expanded to a greater extent, meaning PA3s is designed to be used with them to expand the categories of digital inputs; if used with a DAC+HPA, more comprehensive functions will be achieved.
