What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
FiiO K11
Positive but single-sourced: among whitelisted testers, only SoundGuys published a hands-on review of the exact standard K11 (What Hi-Fi and TechRadar covered only the R2R variant or other FiiO DACs). SoundGuys praised the clean, detailed output, plentiful I/O and compact size, but flagged a clunky menu, over-bright default LED and too-light chassis. No lab measurements taken. (1 sourced review.)
Praised: Clean, detailed output with no noticeable coloration; Plentiful I/O (optical/coax/USB in; 6.4mm + 4.4mm outputs run simultaneously; line out); Compact, desktop-friendly size with Mac-like aesthetics.
Flagged: Clunky, unintuitive menu; changing gain is a 4-step operation; Default LED is too bright blue and awkward to turn off; Too light; feet lack grip so the unit slides when plugging in headphones; external power brick.
AudioQuest DragonFly Cobalt
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.
