How they stack up

iFi Zen DAC 3

The Zen DAC 3 supports higher USB sample rates (768kHz/DSD512) than the FiiO K7 and Topping DX3 Pro+, but delivers far less power, making it a better fit for efficient headphones than the K7's demanding-headphone reach.

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.
