Short answer: the TempoTec Sonata BHD Pro. Both are rated 4.2/5 (#6 and #5 of 14 usb-c dongle DACs), and the TempoTec Sonata BHD Pro costs $69.90 against $89.99 for the TANCHJIM Space, so with nothing between them on measured performance, price settles it.
The case for the TANCHJIM Space: Audio Science Review measured 115 dB SINAD, right at the level where noise and distortion become inaudible, so this dongle is effectively transparent. The catch: It rates below the FiiO KA15 for a similar price, and that rival publishes more than twice the power from its balanced output.
The case for the TempoTec Sonata BHD Pro: Audio Science Review measured a SINAD of 112 dB, clean for nearly all listening. The tradeoff: Its SINAD is lower than most rivals here, and the TRN Black Pearl rates higher with 117 dB and more rated power for less.
Buy the TempoTec Sonata BHD Pro. Both are rated the same, and it costs $20.09 less than the TANCHJIM Space.

The Two Amps and DACs In Full
TANCHJIM Space: $89.99 HiFiGo eBay
Pros: Audio Science Review measured 115 dB SINAD, right at the level where noise and distortion become inaudible, so this dongle is effectively transparent. A rated 230 mW into 32 ohms drives most headphones, and it offers both a 3.5 mm jack and a 4.4 mm balanced output with dual CS43131 DAC chips. Button volume control lets you adjust level on the dongle itself.
Cons: It rates below the FiiO KA15 for a similar price, and that rival publishes more than twice the power from its balanced output. The TRN Black Pearl rates higher and measured cleaner for much less. The 230 mW figure suits most headphones but leaves little headroom for hard to drive planar magnetic models.

TempoTec Sonata BHD Pro: $69.90 Amazon eBay
Pros: Audio Science Review measured a SINAD of 112 dB, clean for nearly all listening. A rated 280 mW into 32 ohms from the 4.4 mm balanced output drives most headphones, and a 3.5 mm output is also included. At 18 g it is easy to keep attached to a phone, and it costs less than the Fosi Audio DS3.
Cons: Its SINAD is lower than most rivals here, and the TRN Black Pearl rates higher with 117 dB and more rated power for less. There is no EQ listed and volume is button controlled. The rated power figure applies to the balanced output only.
