So, how does the FiiO M33 R2R perform once the music starts playing? Amazing, but we all expected no less, didn’t we?

Coming from the M23 or M21, the first thing that hits you isn’t a “wow” moment – it’s a shift. Where those delta-sigma players deliver a presentation that’s clean, detailed, and slightly analytical at times, the M33 R2R trades some of that razor-sharp definition for something rounder, smoother, and undeniably more organic. Notes don’t just start and stop – they bloom, breathe, and decay with a naturalness that immediately sets the R2R apart from its siblings.
