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 Qudelix T71 ranks #32, rated 3.8/5, and costs $229, so there is little reason to consider the other one.
The Khadas Tone2 Pro is the better-sounding option. Audio Science Review measured a SINAD of 118 dB, so its noise and distortion are inaudible. The tradeoff: 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.
What the Qudelix T71 does well: Audio Science Review measured 110 dB SINAD, clean enough for nearly all listening. The tradeoff: The maker does not publish a 32 ohm power figure, so it is hard to judge how well it drives demanding headphones.
Buy the Khadas Tone2 Pro. It is rated higher than the Qudelix T71 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

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.

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.
