#3 Topping A50s Discontinued eBay
Newer model: the Topping A50 III, ranked higher, rated 4.8/5, released Mar 2024. See every Topping A50 generation.
Pros: Audio Science Review measured a SINAD of 121 dB, so its noise and distortion are inaudible and it is effectively transparent. A rated 3,500 mW into 32 ohms is enough for nearly any headphone, including hard to drive planars, with 760 mW into 300 ohms for high impedance models. It offers balanced outputs and RCA inputs.
Cons: Discontinued and replaced by the Topping A50 III. It has no built in DAC, so it needs a separate DAC or source with a line output.
