Topping PA5 Class D Balanced Amplifier 2x125W 4Ω

Topping offers with the PA5 a compact yet powerful and high performance balanced amplifier. It integrates a new generation of optimized Class D amplifier circuit capable of delivering a power of 2x125W under 4Ω, with a high efficiency. This new circuit offers a precise, neutral and rich sound reproduction, with a totally inaudible background noise. The balanced design of the PA5 also allows it to considerably limit its noise level and cancel ground loops.

Fully balanced 

The newly developed Class D amplification circuit uses multiple novel optimization techniques to fully push the performance and output power to the maximum. The new circuit provides crisp, clean and deep sound with completely inaudible noise floor. The fully balanced structure makes PA5 no more hum, no more noise, no more ground loop. 

Simple and efficient connectivity

The PA5 does not overdo its connectivity but proposes a simple and efficient connectivity. Thus, it offers two balanced inputs in 6.35mm TRS stereo jack format. The output is simply done on speaker terminals.

E50 is the best DAC for PA5 

PA5 and E50 have fully matched design language and styles, and signals can transmit in balanced by TRS. 

PA5+E50+L50 this is a fully functional combination 

When you need a more comprehensive system, we recommend a combination of PA5 power amplifier, E50 DAC, and L50 headphone amplifier. In this way, there are corresponding equipment from the digital audio source to driving speakers and headphones. 

D10 Balanced could be best USB DAC for PA5 

D10 Balanced can provide high-fidelity USB decoding and TRS balanced output. When used with PA5, it is equivalent to adding a high-performance USB input to PA5. This combination is simple and efficient.

*** To connect a balanced signal to the input of the PA5, for example those coming from the balanced outputs of the Topping E50, it is necessary to purchase the Topping TCT1 cables separately (click here)
