Short answer: the Luxsin X8. It ranks #30 of 43 DAC and headphone amp combos by measured performance, rated 4.0/5, at $699; the Sennheiser HDV 820 ranks #34, rated 3.6/5, and costs $1,999.95, so there is not much of a tradeoff to weigh.
The Luxsin X8 is the better-sounding pick. Audio Science Review measured 120 dB SINAD, so its noise and distortion are transparent. Watch for: The maker doesn’t publish a 32 ohm power figure, so its headroom for demanding headphones is unknown.
What the Sennheiser HDV 820 does well: Audio Science Review measured a SINAD of 108 dB, clean for nearly all listening. The tradeoff: Sennheiser doesn’t publish a power figure into 32 ohms, so it is hard to judge how well it drives low impedance planar headphones.
Buy the Luxsin X8. It is rated higher than the Sennheiser HDV 820 and costs less, so only choose the other one for a particular feature it does better.

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.

Sennheiser HDV 820: $1,999.95 Sennheiser eBay
Pros: Audio Science Review measured a SINAD of 108 dB, clean for nearly all listening. It has 6.35 mm, 4.4 mm balanced and 4-pin XLR balanced headphone outputs, and accepts USB, optical, coaxial, RCA and XLR inputs, so it can also serve as a standalone amp for another DAC.
Cons: Sennheiser doesn’t publish a power figure into 32 ohms, so it is hard to judge how well it drives low impedance planar headphones. The Loxjie D40 rates higher and measured much cleaner for a small fraction of the price.
