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.
High output power – PA5 could output 140W X 2 at 4ohm load, 10% THD+N.In higher standard of THD+N of 1%, output power will be 125W x 2 at 4ohm load.The high output power and low distortion on load are sufficient for most speakers and applications
PA5+E50+L 50 – 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 andheadphones.
Use with D10 Balanced – 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.
Circuit Protection – Zero pop noise or thumping during turn-on or turn-off. Over-voltage, under-voltage, short-circuit, over-current, over-heat protection are complete
