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 DM-01 ranks #41, rated 2.4/5, and costs $279, which makes this an easy call rather than a real tradeoff.
The Qudelix T71 is the better-sounding choice. 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.
What the xDuoo DM-01 does well: It supports a long list of Bluetooth codecs, including LDAC, aptX Adaptive and LC3, alongside USB-C. Watch for: Audio Science Review measured just 38 dB SINAD, a severe and audible level of noise and distortion.
Buy the Qudelix T71. It is rated higher than the xDuoo DM-01 and costs less, so only choose the other one for a particular feature it 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 DM-01: $279.00 Amazon eBay
Pros: It supports a long list of Bluetooth codecs, including LDAC, aptX Adaptive and LC3, alongside USB-C. A rated 1.5 W into 32 ohms is enough power on paper for most planar magnetic headphones.
Cons: Audio Science Review measured just 38 dB SINAD, a severe and audible level of noise and distortion. There is only a single unbalanced 6.35 mm output, and the Loxjie D30 rates far higher and measures transparent for much less.
