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.
Topping DX5 II
Only one whitelisted tester, TechRadar, published a hands-on review of the exact Topping DX5 II. TechRadar rates it a near-excellent budget DAC/amp (verdict 'generally excellent'), praising its poised, detailed and dynamic sound, exemplary build and comprehensive specification at $299, while flagging a tendency toward top-end brightness. (1 sourced review, 1 lab-tested.)
Praised: Poised, spacious, detailed and dynamic sound with strong low-frequency control; Exemplary build and finish quality across black, silver and white options; Comprehensive specification and flexibility (DAC, preamp and headphone amp) at an aggressive $299 price.
Flagged: Treble can tend toward brightness/edginess, making it picky about partnering equipment; Supplied remote control handset feels less tactile and interesting than the unit itself.
