How we ranked these headphone amps
Every pick has at least 100 customer ratings on Amazon and a listing with real specifications. The order mixes two things: how each model compares on the specs below (higher share of the best value in this group scores more), and how widely it is bought. The spec score runs from 9.0 to 9.8 and only compares these picks with each other. A spec the listing does not state is left out and the other specs are re-weighted; a listing with fewer than 2 stated specs is scored at half. We do not test gear in person. Full method.
- Built-in DAC weight 2
- Balanced output weight 1
- USB connection weight 1
- Runs on batteries weight 1

Count the headphone channels you need
Channel count decides how many listeners share one source. The Bolanle PH8000 and the STABCL amp each split one input to 8 headphone channels with a volume control on each channel. The Monoprice Liquid Spark gives a single channel with an RCA input and a 1/4-inch output. Count the listeners you need to feed, and pick the channel count that covers them.

The Monoprice Liquid Spark takes an RCA input and adds preamp output RCAs. The STABCL amp takes 1/4-inch and 1/8-inch plugs with a mono and stereo switch. Match the jacks to your source and headphones before you buy.
