Short answer: the Tanchjim Luna. It ranks #20 of 43 DAC and headphone amp combos by measured performance, rated 4.3/5, at $118.99; the Khadas Tone2 Pro ranks #22, rated 4.2/5, and costs $159, so there is not much of a tradeoff to weigh.
The case for the Tanchjim Luna: Audio Science Review measured 116 dB SINAD, so its noise and distortion are inaudible. The tradeoff: Power drops to a rated 54 mW into 300 ohms, which is thin for high impedance headphones, and planar magnetic models may want more than 285 mW.
What the Khadas Tone2 Pro does well: Audio Science Review measured a SINAD of 118 dB, so its noise and distortion are inaudible. Watch for: 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.
Buy the Tanchjim Luna. It is rated higher than the Khadas Tone2 Pro 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
Tanchjim Luna: $118.99 Apos Audio eBay
Pros: Audio Science Review measured 116 dB SINAD, so its noise and distortion are inaudible. A rated 285 mW balanced into 32 ohms drives most headphones, and it has both a 3.5 mm jack and a 4.4 mm balanced output fed by dual CS43198 DAC chips. It rates on par with the Chord Mojo 2 and measured cleaner for far less.
Cons: Power drops to a rated 54 mW into 300 ohms, which is thin for high impedance headphones, and planar magnetic models may want more than 285 mW. USB-C is the only input, so there is no optical or Bluetooth. The Schiit Magni Unity with Mesh DAC rates higher and publishes far more power at 32 ohms, though it costs more.

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.
