Short answer: the SMSL D200. It ranks #17 of 30 DACs by measured performance, rated 4.8/5, at $319. The Soncoz LA-QXD1 ranks #21, rated 4.6/5, at $219, $100 cheaper, not enough of a saving to outweigh the sound-quality gap.
What the SMSL D200 does well: Audio Science Review measured a SINAD of 116 dB, so its noise and distortion are inaudible. The tradeoff: The SMSL D-6S rates the same and measures cleaner at 122 dB for less.
The case for the Soncoz LA-QXD1: Audio Science Review measured 114 dB SINAD, clean for nearly all listening. Watch for: It is a DAC only with no headphone output and no Bluetooth input.
Buy the SMSL D200. It is rated higher, and the $100 you would save on the Soncoz LA-QXD1 does not close the gap.

The Two Amps and DACs In Full
SMSL D200: $319.00 Amazon eBay
Pros: Audio Science Review measured a SINAD of 116 dB, so its noise and distortion are inaudible. It feeds powered speakers or an amp through RCA or balanced XLR outputs, and a volume knob and remote let it work as a preamp. Inputs cover USB, optical, coaxial and Bluetooth with LDAC, aptX HD and AAC.
Cons: The SMSL D-6S rates the same and measures cleaner at 122 dB for less. Its SINAD trails the 123 dB of the Topping D70 Pro SABRE, though both are well past the point of audibility. At 1,214 g, it is a full-size box.
