Short answer: the Fosi Audio Q6. It ranks #25 of 30 DACs by measured performance, rated 4.5/5, at $84.99; the Topping D10s ranks #27, rated 4.3/5, and costs $109, so there is little reason to consider the other one.
What the Fosi Audio Q6 does well: Audio Science Review measured 115 dB SINAD, so its noise and distortion are transparent. The catch: There are no balanced outputs and no volume control, so it needs an amp or speakers with their own volume.
Why pick the Topping D10s: Audio Science Review measured a SINAD of 112 dB, so it is clean for nearly all listening. The tradeoff: USB is the only input, so it cannot accept a TV, console or CD transport over optical or coaxial.
Buy the Fosi Audio Q6. It is rated higher than the Topping D10s and costs less, so only choose the other one for a particular feature it does better.

The Two Amps and DACs In Full
Fosi Audio Q6: $84.99 Amazon eBay
Pros: Audio Science Review measured 115 dB SINAD, so its noise and distortion are transparent. It takes USB-C, optical and coaxial inputs and feeds an amp or powered speakers over RCA, with a separate sub out for adding a subwoofer. It matches the rating of the SMSL PS200 PRO for slightly less.
Cons: There are no balanced outputs and no volume control, so it needs an amp or speakers with their own volume. The SMSL SU-2 rates higher with lower measured distortion and XLR outputs for a little more.

Topping D10s: $109.00 Amazon eBay
Pros: Audio Science Review measured a SINAD of 112 dB, so it is clean for nearly all listening. It takes USB from a computer and feeds an amplifier or powered speakers over RCA, and it can also pass the signal on through coaxial or optical outputs to another device.
Cons: USB is the only input, so it cannot accept a TV, console or CD transport over optical or coaxial. It has no balanced outputs and no volume control, and the SMSL PS200 PRO rates higher and measured cleaner for less.
