Know before you buy
Yes, with an output power of 3500mW x 2 at 32Ω, the A50 III is designed to handle demanding headphones with ease. Its three-step gain switch allows you to optimize the power delivery for both sensitive IEMs and power-hungry over-ear models.
The 6.35mm jack is a standard single-ended output for most traditional headphones, while the 4.4mm jack provides a balanced connection. Using the balanced 4.4mm output can offer better channel separation and reduced interference if your headphones support a balanced cable.
No, the A50 III is a dedicated analog headphone amplifier. You will need to connect an external DAC to the RCA or TRS inputs to convert your digital audio files into an analog signal.
The NFCA (Nested Feedback Composite Amplifier) module is engineered to provide an exceptionally low noise floor and minimal distortion. This ensures that the amplifier remains transparent, allowing you to hear the fine details of your music without added coloration or background hiss.
Yes, the 12V trigger output allows the A50 III to synchronize power with other compatible audio devices. When you turn the amplifier on or off, it will automatically send a signal to trigger your connected equipment, simplifying your desktop setup.
The chassis is crafted from a solid block of aluminum, which provides excellent durability and a premium feel. Beyond its appearance, the metal construction acts as a shield to protect the internal circuitry from electromagnetic interference, ensuring a cleaner audio signal.
