#21 FiiO K5 Discontinued eBay
Pros: Audio Science Review measured a SINAD of 108 dB, so noise and distortion stay well below audibility in normal listening. A rated 1,500 mW into 32 ohms is enough for nearly any headphone, including hard to drive planars. It offers RCA, player dock 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.
