Short answer: the Tanchjim Luna. It ranks #20 of 43 DAC and headphone amp combos by measured performance, rated 4.3/5, at $118.99. The Loxjie D30 ranks #31, rated 3.9/5, at $111.20, $7.79 cheaper, not enough of a saving to outweigh the sound-quality gap.
The Tanchjim Luna is the better-sounding pick. Audio Science Review measured 116 dB SINAD, so its noise and distortion are inaudible. The catch: Power drops to a rated 54 mW into 300 ohms, which is thin for high impedance headphones, and planar magnetic models may want more than 285 mW.
What the Loxjie D30 does well: Audio Science Review measured a SINAD of 119 dB, so its noise and distortion are inaudible. The catch: Loxjie doesn’t publish an output power figure into 32 ohms, so it is hard to know which headphones it can drive.
Buy the Tanchjim Luna. It is rated higher, and the $7.79 you would save on the Loxjie D30 does not close the gap.

The Two Amps and DACs In Full
Tanchjim Luna: $118.99 Apos Audio eBay
Pros: Audio Science Review measured 116 dB SINAD, so its noise and distortion are inaudible. A rated 285 mW balanced into 32 ohms drives most headphones, and it has both a 3.5 mm jack and a 4.4 mm balanced output fed by dual CS43198 DAC chips. It rates on par with the Chord Mojo 2 and measured cleaner for far less.
Cons: Power drops to a rated 54 mW into 300 ohms, which is thin for high impedance headphones, and planar magnetic models may want more than 285 mW. USB-C is the only input, so there is no optical or Bluetooth. The Schiit Magni Unity with Mesh DAC rates higher and publishes far more power at 32 ohms, though it costs more.

Loxjie D30: $111.20 Amazon eBay
Pros: Audio Science Review measured a SINAD of 119 dB, so its noise and distortion are inaudible. It combines a DAC and headphone amp in one box and adds Bluetooth with SBC and aptX. It costs relatively little for that measured performance.
Cons: Loxjie doesn’t publish an output power figure into 32 ohms, so it is hard to know which headphones it can drive. Its Bluetooth lacks AAC and LDAC. The SMSL DS20 rates clearly higher, with a published 500 mW into 32 ohms and a balanced output, though it costs more.
