Short answer: the Neutron HiFi DAC V1. It ranks #33 of 43 DAC and headphone amp combos by measured performance, rated 3.7/5, at $177; the Leckerton Audio UHA-6S.MKII ranks #40, rated 2.5/5, and costs $239, which makes this an easy call rather than a real tradeoff.
The Neutron HiFi DAC V1 is the better-sounding pick. 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. Watch for: Neutron doesn’t publish a power figure into 32 ohms, and it has only a 3.5 mm output with no balanced option.
The case for the Leckerton Audio UHA-6S.MKII: It is a portable battery powered DAC and amp with micro USB, optical, coaxial and 3.5 mm analog inputs, lasting 10 hours from digital sources and 30 hours in analog mode. The catch: It is rated for only 55 mW into 32 ohms with its stock op amp, which suits in-ear monitors and easy headphones only, and sensitive in-ears may reveal hiss at 94 dB SINAD.
Buy the Neutron HiFi DAC V1. It is rated higher than the Leckerton Audio UHA-6S.MKII and costs less, which makes it the one to get unless you need something the other one does better.

Leckerton Audio UHA-6S.MKII: $239 Leckerton Audio eBay
Pros: It is a portable battery powered DAC and amp with micro USB, optical, coaxial and 3.5 mm analog inputs, lasting 10 hours from digital sources and 30 hours in analog mode. Audio Science Review measured a SINAD of 94 dB, fine for most headphones.
Cons: It is rated for only 55 mW into 32 ohms with its stock op amp, which suits in-ear monitors and easy headphones only, and sensitive in-ears may reveal hiss at 94 dB SINAD. It has no balanced output and still uses micro USB. The Pro-Ject Pre Box S2 Digital rates higher and measures cleaner, though it costs more.
