Back and better than ever

Meet the third generation of the TOPPING A50 series, the A50 III Desktop Headphone Amp, which builds on the foundation of its predecessors to deliver an even better audio experience. This generation boasts a THD+N of less than 0.00006%, a dynamic range over 144dB, and an impressive output of 3500mW x 2 @32Ω. Featuring the NFCA (Nested Feedback Composite Amplifier) module and a 3-step gain switch, the A50 III drives a wide range of headphones and IEMs with world-class clarity.

Ultra-high performance in every note

The heart of the A50 III is the advanced NFCA (Nested Feedback Composite Amplifier) module, shared with its predecessor, the A50s. This cutting-edge technology ensures stellar DC and AC performance, driving even low-impedance headphones without breaking a sweat.

Robust machined aluminium shell

Precision is key in the creation of the A50 III, which boasts a machined shell meticulously carved from a solid block of aluminium. This process not only offers superior electromagnetic shielding, but provides a smooth, refined look and exceptional strength.

Putting the “I/O” in audio

Offering both 6.35mm single-ended and 4.4mm balanced headphone jacks, alongside RCA and TRS inputs, the A50 III adapts seamlessly to your audio setup. Its versatile connection options ensure you can easily switch between input and output combinations, however you like to listen.

Calling all cans and IEMs

With three gain settings and an ultra-low noise floor, the A50 III caters to any headphone, from sensitive IEMs to power-hungry over-ears. Its robust output ensures your music always sounds its best, free from distortion even at peak levels.

Purely powerful

Featuring a powerful output of 3500mW x2 @32Ω, the A50 III guarantees your headphones reach their full potential. Combined with its low distortion rate, this amp delivers clean, powerful sound that stays true to the original recording.

Synchronised and simplified

The 12V trigger output allows the A50 III to power on and off in sync with your other devices, including its perfect match, the D50 III.
