Where the two actually differ on the specs we track (4 of 11). Matching specs are omitted.
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Two whitelisted testers, What Hi-Fi and TechHive, reviewed this exact DAC; both praise its clean, precise, detailed sound in a tiny plug-and-play package and rate it among the best small DACs, while flagging the premium price. Neither ran instrumented measurements, so all findings are subjective listening. No SoundGuys or PCMag review found. (2 sourced reviews.)
Praised: Clean, precise, highly detailed sound with improved clarity over built-in DACs; Compact, pocket-sized, plug-and-play with no external power needed; Greatly improved timing and dynamics.
Flagged: Premium price for a USB-stick-sized DAC; Included DragonTail adaptor fits loosely and pulls out of phones; Status light shows green for sub-44.1kHz files, so it doesn't distinguish MP3 from CD quality.
