Headphone Amplifiers Topping

The Topping A90D Headphone amplifier builds on the success of the A90 model reconfiguring the NFCA module geometry to implement high performance discrete amplification. Exceeding previous designs the A90D delivers a powerful output capable of driving power hungry low impedance headphones and highly sensitive in-ear monitors alike.The internal components achieve astonishingly low noise levels ensuring that the signal remains accurate without colouration from unwanted distortion. The Topping A90D is a must-have for desktop scale high-fidelity audio.

The Topping A50s Desktop Headphone Amplifier uses trickle down NFCA technology from the flagship A90 model sharing in the high detail high current output to drive a wide range of headphones. The two gain settings between 0dB and 6dB (or 6dB / 12dB with 4.4mm balanced output) let you adjust the A50s to match your home listening setup. With extremely low noise a mere 0.3uVrms this headphone amplifier ensures the signal from your high resolution source remains unadulterated without unwanted or electrical sound leaching into the signal. The Topping A50s sets the stage to allow sensitive or power hungry headphones alike to truly perform with a maximum output power of 3500mW per channel.

6.35mm SE & 4.4mm balanced output ---Although there is only a single-ended input, A50s has a bilt-in balanced amp circuit. Therefore, it can drive single-ended head- phones by 6.35mm output, and drive balanced headphones by 4.4mm balanced output.
Wide range of adaptation to headphones ---A50s has a high voltage swing of 42Vp-p, power of 3500mW per channel when both channels are driven and output impedance of less than 0. 1Ohm. It easily drives power-hungry headphones with a wide range of different impedance.
2 step gain settings, adapt to various sensitivities ---A50s is equipped with two gain settings of 0dB/6dB at SE out- put(6dB/12dB at balanced output). Wide range of gain settings and …

The Topping A30 Pro Desktop Headphone Amplifier is optimised to drive most headphone types with uncompromising precision and accuracy. No matter how power-hungry your cans are the A30 Pro is suited to accommodate thanks to 3 separate gain settings and an ultra-low noise profile. Its perfect for sensitive IEMs and demanding over-ears alike. Single-ended and balanced inputs allow you to have versatile source options whilst 4-pin-XLR 4.4mm and 6.35mm outputs offer complete amplification for all major headphone types. An input pass-through function allows you to keep your A30 Pro in your signal chain for use with active speakers or DACs with a preamp functionality. With impedance as low as 20 ohms …
