TOPPING A50 III
Desktop symmetrical NFCA headphone amplifier
The long-awaited A50 III model from Topping is the third generation of the A50 headphone amplifier series, featuring the high-quality version of the NFCA circuit design. It offers three gain settings to perfectly drive headphones with different impedances. The total harmonic distortion plus noise (THD+N) is below 0.00006%, and the dynamic range reaches an impressive 144 dB. The dual-channel output power reaches 3500 mW into a 32 ohm load, providing powerful headphone-driving capability. The aluminum-housed A50 III supports both balanced and RCA inputs, as well as 6.35mm SE and 4.4mm balanced outputs.
Additionally, the device has a 12V Trigger input port that can be connected to other devices supporting this feature for synchronized switching. It is a perfect match for the D50 III desktop DAC (digital-to-analog converter) model developed alongside it!
