How they stack up

FiiO K7

The K7 offers more balanced power (2000mW) than the iFi Zen DAC 3 or Topping DX3 Pro+, making it the better choice for hard-to-drive headphones, though it lacks the Zen DAC 3's higher-resolution USB support and the Schiit Hel 2E's microphone input.

Topping DX3 Pro+

The DX3 Pro+ offers the most amp power (1.8W) of the compact units here and adds Bluetooth LDAC the FiiO K7 lacks, but its neutral tuning is less forgiving than the iFi Zen DAC 3's warmer presentation.
