Topping's long-awaited A50 III is the third generation of the A50 headphone amplifier series, featuring a high-end version of the NFCA circuit design. It offers three gain settings to perfectly drive earphones and headphones with different impedances. Distortion THD+N is below 0.00006% and dynamic range reaches an impressive 144 dB. The dual-channel output power reaches 3500 mW at 32 ohms load, providing powerful headphone drive capability. The A50 III is built in sturdy aluminium housing and supports symmetrical and RCA inputs, as well as 6.35mm SE and 4.4mm symmetrical outputs.
In addition, the amplifier has a 12V Trigger input port that can be connected to other devices supporting this feature for synchronous switching. The perfect companion for the D50 III desktop DAC (digital-to-analogue converter) that it was developed with!
