Short answer: the Chord Mojo 2. It ranks #21 of 43 DAC and headphone amp combos by measured performance, rated 4.3/5, at $566.86; the Luxsin X9 ranks #29, rated 4.0/5, and costs $1,099, so there is little reason to consider the other one.
The case for the Chord Mojo 2: Audio Science Review measured a SINAD of 110 dB, which is clean for nearly all listening. Watch for: It costs far more than the TRN Black Pearl, which rates higher and measured cleaner at 117 dB.
What the Luxsin X9 does well: Audio Science Review measured a SINAD of 121 dB, so its noise and distortion are inaudible. The tradeoff: Luxsin doesn’t publish an output power figure into 32 ohms.
Buy the Chord Mojo 2. It is rated higher than the Luxsin X9 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
Chord Mojo 2: $566.86 Amazon eBay
Pros: Audio Science Review measured a SINAD of 110 dB, which is clean for nearly all listening. A rated 600 mW into 30 ohms is enough for most planar magnetic headphones, unusual muscle for something this portable. It takes USB-C, Micro-USB, optical and coaxial inputs, offers both 3.5 mm and 4.4 mm outputs, and includes built-in DSP tone control.
Cons: It costs far more than the TRN Black Pearl, which rates higher and measured cleaner at 117 dB. The Fosi Audio DS3 also matches its rating for much less. At 185 g it is much bigger and heavier than a typical dongle, so it is less convenient to carry with a phone.

Luxsin X9: $1,099.00 Amazon eBay
Pros: Audio Science Review measured a SINAD of 121 dB, so its noise and distortion are inaudible. Its input list is unusually broad, covering USB-B, USB-C, optical, coaxial, HDMI ARC, RCA and Bluetooth, with RCA, XLR and a dedicated subwoofer output that suit a TV or desktop speaker system. Headphone outputs include 6.35 mm, 4.4 mm balanced and 4-pin XLR.
Cons: Luxsin doesn’t publish an output power figure into 32 ohms. It costs several times more than the Loxjie D40, which rates the same and measures slightly cleaner. Bluetooth tops out at AAC, and at 3,720 g and 300 mm wide it is large and heavy.
