Short answer: the Khadas Tone2 Pro. It ranks #22 of 43 DAC and headphone amp combos by measured performance, rated 4.2/5, at $159. The Loxjie D30 ranks #31, rated 3.9/5, at $111.20, $47.80 cheaper, which does not close the gap in measured performance.
The Khadas Tone2 Pro is the better-sounding choice. Audio Science Review measured a SINAD of 118 dB, so its noise and distortion are inaudible. The catch: Khadas rates it at 211 mW into 32 ohms on the balanced output, enough for most headphones but short of what many planar magnetic models want.
Why pick the Loxjie D30: 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 Khadas Tone2 Pro. It is rated higher, and saving $47.80 with the Loxjie D30 does not make up for the sound-quality gap.

The Two Amps and DACs In Full
Khadas Tone2 Pro: $159.00 Amazon eBay
Pros: Audio Science Review measured a SINAD of 118 dB, so its noise and distortion are inaudible. It offers 3.5 mm and 4.4 mm balanced headphone outputs, RCA and balanced RCA line outputs, USB-C and coaxial inputs, and optional Bluetooth through an add-on dongle, and it rates higher than the Woo Audio WA11 Topaz for far less.
Cons: Khadas rates it at 211 mW into 32 ohms on the balanced output, enough for most headphones but short of what many planar magnetic models want. The Fosi Audio SK02 matches its rating with much more balanced power for less, and Bluetooth requires buying the separate dongle.

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.
