#12 SMSL M500 MKII Discontinued eBay
Pros: Audio Science Review measured a SINAD of 121 dB, so its noise and distortion are inaudible and it is effectively transparent. A rated 1,000 mW into 32 ohms is enough for most headphones. It offers Bluetooth input with LDAC and USB, optical, coaxial inputs.
Cons: Discontinued, so it is mainly found used. There is no balanced headphone output.
