#20 Topping NX3s Discontinued eBay
Pros: Audio Science Review measured a SINAD of 113 dB, so noise and distortion stay well below audibility in normal listening. A rated 545 mW into 32 ohms is enough for most headphones, with 100 mW into 300 ohms for high impedance models. It offers 3.5 mm inputs.
Cons: Discontinued, so it is mainly found used. There is no balanced headphone output. It has no built in DAC, so it needs a separate DAC or source with a line output.
