Topping A90 Headphone Amplifier Released

Topping A90

Following their flagship DAC D90, Topping has just released a matching head-amp Topping A90. Dimensions and styling are unexpectedly in line with D90 so these two make a stylish looking stack.

Topping brags that A90 is equipped with ultra-high performance NFCA modules, Voltage current hybrid feedback architecture with UHGF (Ultra High Gain Feedback) technology. It provides excellent AC and DC performance. The AMP output has an ultra-low impedance of < 0.1 Ohms, while high output current capability allows it to drive low impedance headphones with ease. Furthermore, ultra-low noise of <0.2 uVrms is supposed to drive the most sensitive IEMs without producing any audible background noise.
