Short answer: the Gustard A20H. It ranks #25 of 43 DAC and headphone amp combos by measured performance, rated 4.2/5, at $752. The Luxsin X8 ranks #30, rated 4.0/5, at $699, $53 cheaper, which does not close the gap in measured performance.
Why pick the Gustard A20H: A rated 2.4 W balanced into 32 ohms and 264 mW into 300 ohms is enough for planar magnetic and high impedance headphones alike. The tradeoff: Its 103 dB SINAD trails many cheaper rivals, and the Tanchjim Luna rates higher with cleaner measurements for a small fraction of the price.
What the Luxsin X8 does well: Audio Science Review measured 120 dB SINAD, so its noise and distortion are transparent. The catch: The maker doesn’t publish a 32 ohm power figure, so its headroom for demanding headphones is unknown.
Buy the Gustard A20H. It is rated higher, and the $53 saving on the Luxsin X8 is not enough to make up the difference.

Gustard A20H: $752 HiFiGo eBay
Pros: A rated 2.4 W balanced into 32 ohms and 264 mW into 300 ohms is enough for planar magnetic and high impedance headphones alike. Inputs include USB, I2S over HDMI, AES/EBU, coaxial and optical, with RCA and XLR line outputs and a 60 step relay volume control. Audio Science Review measured 103 dB SINAD, clean enough for nearly all listening.
Cons: Its 103 dB SINAD trails many cheaper rivals, and the Tanchjim Luna rates higher with cleaner measurements for a small fraction of the price. There is no Bluetooth input, and at 6 kg it is a very large and heavy unit for what it delivers.

Luxsin X8: $699.00 Amazon eBay
Pros: Audio Science Review measured 120 dB SINAD, so its noise and distortion are transparent. It is packed with features: 6.35 mm, 4.4 mm and 4-pin XLR headphone outputs, USB, optical, coaxial, I2S, Bluetooth and Wi-Fi inputs, a touchscreen, and parametric EQ with headphone correction through an app.
Cons: The maker doesn’t publish a 32 ohm power figure, so its headroom for demanding headphones is unknown. The SMSL DS20 rates higher with a published 500 mW for far less, and at 2,750 g it is a very large desktop unit.
