#16 SMSL DS20: $189.99 Amazon eBay
Pros: Audio Science Review measured a SINAD of 116 dB, so its noise and distortion are inaudible. A rated 500 mW into 32 ohms and 120 mW into 300 ohms drives most headphones, through 3.5 mm or 4.4 mm balanced outputs. At 17 mm thick and 275 g, it is slim enough to sit on a desk or travel in a bag.
Cons: It only accepts USB-C, with no optical, coaxial or Bluetooth input, and volume is set with buttons. The Topping DX1 II rates higher, measures cleaner and adds optical input for less. The Fosi Audio ZH3 offers far more rated power for a similar price.
