Topping A50 Headphone Amp
Effortless Amplification With 3 Outputs
The perfect partner for any pair of high-impedance headphones, DAC, or both, the Topping A50 headphone amp delivers powerful amplification to fit any setup. This portable headphone amplifier includes three different headphone outputs—a 6.35-millimeter single end, a 3.5-millimeter single end, and a 2.5-millimeter balanced end—for all types of headphones. It can output an impressive 2200 mW at 64 ohms out of the balanced 2.5-millimeter jack, or 1110 mW at 32 ohms out of the 3.5- and 6.35-millimeter outputs. Sturdy and space-efficient, the A50 pairs well with any DAC—particularly the Topping D50 or D50s.
Note: At checkout, choose a US or an EU plug. Both options are available in black and silver.
