Short answer: the Qudelix T71. It ranks #32 of 43 DAC and headphone amp combos by measured performance, rated 3.8/5, at $229; the xDuoo XA-10 ranks #35, rated 3.6/5, and costs $479, so there is little reason to consider the other one.
What the Qudelix T71 does well: Audio Science Review measured 110 dB SINAD, clean enough for nearly all listening. Watch for: The maker does not publish a 32 ohm power figure, so it is hard to judge how well it drives demanding headphones.
Why pick the xDuoo XA-10: It is a very flexible DAC and amp with USB, optical, coaxial and Bluetooth inputs, and Bluetooth supports SBC, AAC, aptX, aptX LL, aptX HD and LDAC. The tradeoff: Audio Science Review measured a SINAD of 90 dB, which is fine for most headphones but may reveal hiss or noise with sensitive in-ear monitors.
Buy the Qudelix T71. It is rated higher than the xDuoo XA-10 and costs less, which makes it the one to get unless you need something the other one does better.

The Two Amps and DACs In Full
Qudelix T71: $229.00 Qudelix eBay
Pros: Audio Science Review measured 110 dB SINAD, clean enough for nearly all listening. A built in 20 band parametric or graphic equalizer lets you tune your headphones, and it offers 3.5 mm plus 2.5 mm and 4.4 mm balanced outputs. Its battery runs 4 to 10 hours, and it weighs 75 g.
Cons: The maker does not publish a 32 ohm power figure, so it is hard to judge how well it drives demanding headphones. USB-C is the only input. The Loxjie D30 rates higher and measured cleaner for less.

xDuoo XA-10: $479.00 Amazon eBay
Pros: It is a very flexible DAC and amp with USB, optical, coaxial and Bluetooth inputs, and Bluetooth supports SBC, AAC, aptX, aptX LL, aptX HD and LDAC. A rated 4,000 mW into 32 ohms from the balanced outputs drives nearly any headphone, and it offers 6.35 mm, 4.4 mm and 4-pin XLR headphone jacks.
Cons: Audio Science Review measured a SINAD of 90 dB, which is fine for most headphones but may reveal hiss or noise with sensitive in-ear monitors. The Loxjie D40 rates higher and measures far cleaner for less. The rated power figure applies to the balanced outputs, so the 6.35 mm jack delivers less.
