FiiO's first R2R DAPFiiO’s first R2R-based portable player brings a ladder DAC architecture into a compact, Android-powered device built for everyday listening and desktop duty.
A Snapdragon 680 platform brings fantastic UI, the 5.5-inch 1080p display is easy on the eyes, and a full Ti-based multi-stage amplifier delivers clean power through both balanced and single-ended outputs.
The M33 R2R uses a true R2R DAC architecture rather than a conventional delta-sigma design. Resistor ladder conversion emphasizes precise voltage steps and natural timing, which many listeners associate with a grounded, analog-leaning presentation.
FiiO pairs this with selectable OS and NOS modes, letting you choose between Oversampling for precision or Non-Oversampling for a more direct signal path.
Flagship amplifier topologyThe internal amplification borrows from FiiO’s higher-end designs, using a full-series titanium multi-stage layout.
The goal is consistency across gain stages and lower noise under load. It translates into stable output for both sensitive in-ear monitors and harder-to-drive full-size headphones, whether you are listening on the go or at a desk.
Android platform with headroomA Snapdragon 680 processor handles the Android operating system with enough margin for modern streaming apps and local playback.
Large internal storage support means fewer compromises when carrying high-resolution libraries, while system responsiveness stays predictable during daily use.
Clear, compact displayThe 5.5-inch screen runs at 1920 × 1080 resolution, providing sharp text and album art without pushing the chassis into oversized territory.
Touch response is direct, making browsing large libraries and navigating apps straightforward.
Flexible outputs and signal rolesConnectivity covers most portable and home scenarios. You get 3.5mm and 4.4mm outputs that can operate as either headphone outs or fixed line-level outputs, plus a low-jitter coaxial digital output and USB audio.
The player can function as a portable source, a pre-amp, or a compact digital transport.
Desktop mode and dual power pathsDual USB power inputs separate charging from playback when needed, reducing electrical interference during longer listening sessions.
Desktop mode is designed for stationary use, letting the player run as a small-footprint DAC and pre-amp without leaning on the battery.
Battery life with fast, cool chargingA 4,400mAh battery supports up to 12.5 hours of playback. When it is time to recharge, the 25W low-temperature charge pump technology focuses on speed while keeping heat under control, which helps preserve long-term battery health.
