Short answer: the Topping DX1 II. It ranks #6 of 43 DAC and headphone amp combos by measured performance, rated 4.9/5, at $119; the Tanchjim Luna ranks #20, rated 4.3/5, at $118.99. Close enough in price that the sound-quality gap is the deciding factor.
The Topping DX1 II is the better-sounding option. Audio Science Review measured a SINAD of 121 dB, so its noise and distortion are inaudible. The tradeoff: Inputs are limited to USB-C and optical, with no coaxial or Bluetooth.
The case for the Tanchjim Luna: Audio Science Review measured 116 dB SINAD, so its noise and distortion are inaudible. The catch: 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.
Buy the Topping DX1 II. It is rated higher, and the $0.01 saving on the Tanchjim Luna is not enough to make up the difference.

Topping DX1 II: $119.00 Amazon eBay
Pros: Audio Science Review measured a SINAD of 121 dB, so its noise and distortion are inaudible. A rated 1,000 mW into 32 ohms from the 4.4 mm balanced output handles most planar magnetic headphones, and a 10-band parametric EQ and a 3.5 mm headset jack with mic support are included. It rates the same as the D&A Alpha Pro for a fraction of the cost.
Cons: Inputs are limited to USB-C and optical, with no coaxial or Bluetooth. Its 230 mW into 300 ohms is modest beside the Topping DX5 II, which rates the same with far more power but costs more. No volume knob is listed.

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.
