## What reviewers say

**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.)
