Topping PA3s-3

Topping has the widest collection of desktop audio gears. They offer quality performance at all the different price segments. We personally love their E30+L30 Stack that offered good performance for both IEMs as well as Headphones. Today, Topping has introduced its latest desktop power amplifier, the brand new Topping PA3S. PA3S offers a fully balanced amplifier architecture with dual independent MA12070 Class D power amplifier chips, one for each channel producing a clean, low-distortion output for your HiFi speaker systems. It has more than adequate power required to easily drive bookshelf speakers with great clarity. Topping PA3S is available worldwide for just 150$, yes just 150$ to bring high-resolution amplification to your speaker systems.

Topping PA3s-1

Topping PA3S has an output power rating of up to 80Wx2 @ 4Ω with THD+N at 10%. In lower distortion THD+N 1% level, the PA3S outputs 65Wx2 @4Ω. It is more than adequate to power up bookshelf speakers and even some full-size floor speakers. Add Topping PA3S to your HiFi speaker system and fill them with life!!

Topping PA3s-2

PA3S offers both Single-Ended and Balanced input options for its users. The device has RCA single-ended as well as TRS balanced input options. Topping has recently launched multiple desktop DACs with TRS balanced connection support including the latest D10 Balanced, and E50 DAC systems. Adding PA3S with D10 Balanced or E50 makes a fully balanced Desktop Stack for your HiFi speaker systems.
