Short answer: the Loxjie D30. It ranks #31 of 43 DAC and headphone amp combos by measured performance, rated 3.9/5, at $111.20; the Neutron HiFi DAC V1 ranks #33, rated 3.7/5, and costs $177, which makes this an easy call rather than a real tradeoff.
The case for the Loxjie D30: Audio Science Review measured a SINAD of 119 dB, so its noise and distortion are inaudible. The tradeoff: Loxjie doesn’t publish an output power figure into 32 ohms, so it is hard to know which headphones it can drive.
Why pick the Neutron HiFi DAC V1: Audio Science Review measured a SINAD of 111 dB, clean for nearly all listening, and at 0 lbs (13 g) it is a tiny USB-C dongle. The catch: Neutron doesn’t publish a power figure into 32 ohms, and it has only a 3.5 mm output with no balanced option.
Buy the Loxjie D30. It is rated higher than the Neutron HiFi DAC V1 and costs less, so only choose the other one for a particular feature it does better.

The Two Amps and DACs In Full
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.

Neutron HiFi DAC V1: $177 Neutron HiFi eBay
Pros: Audio Science Review measured a SINAD of 111 dB, clean for nearly all listening, and at 13 g it is a tiny USB-C dongle. Its built-in parametric equalizer with 10 to 40 bands lets you correct a headphone’s frequency response without software on your phone or computer.
Cons: Neutron doesn’t publish a power figure into 32 ohms, and it has only a 3.5 mm output with no balanced option. The Loxjie D30 rates higher and measured cleaner for less.
