Giant power and 3 gain levels

The power of the A50III from Topping can do everything. From 32 Ohms headphones with a capacity to emit up to 3500mW x 2 and up to 760mW x 2 at 300 Ohms over a THD < 0.01%.


The amplifier integrates two headphone outputs: one in 6.35mm jack and another balanced 4.4mm. In addition, a button located on the front panel allows you to select the 3-level gain settings for the headphone outputs.

All connections and compatibility with D50III
