Originally designed for desktop equipment, the M33 R2R Portable Hi-Res Lossless Music Player from FiiO features a fully differential 24-bit R2R array for lossless audio quality with analog-like warmth. A host of high-end internal components is utilized to give your music a natural and expansive soundstage with exceptional clarity. Powerful amps can drive most any headphone through the 3.5mm and 4.4mm outputs. You can also stream music via two-way Bluetooth or use the M33 R2R as a desktop DAC. Access files from 128GB of storage or stream via Wi-Fi, navigating tracks and apps using the built-in 1080p 5.5" touchscreen. Enjoy your audiophile-grade music all day with up to 15.5 hours of playback.
Multi-Stage Audio
A pre-amp stage with TI op-amps are engineered to produce a natural and expansive soundstage, while INA1620 amp chips in a parallel configuration are able to produce up to 1100mW+1100mW of balanced output. This is enough power to support everything from sensitive IEMs or over-ear headphones.
Digital Audio Purification
Using the FiiO M27-derived proprietary DAPS (Digital Audio Purification System), the M33 R2R can efficiently produce high-quality digital audio. A high-capacity FPGA and dual custom femtosecond crystal oscillators are also used to achieve precise audio with ultra-low jitter.
Manual and Auto EQ
Adjust the sound of your music using the global 10-band PEQ and granular, per-band customization. For easier adjustment simply select the Pop, Jazz, or Classic EQ presets, or activate Auto EQ. Auto EQ automatically makes adjustments by matching the frequency curve of your headphones.
Playback and Listening
You have many ways to play music with the M33 R2R DAP. At home, you can connect to Wi-Fi and stream lossless audio from supported online services. When on the go, you can stream via Bluetooth or play files within the DAP's 128GB of built-in storage. You can connect almost any type of headphone to the 3.5mm or 4.4mm outputs or use two-way Bluetooth support to stream to an optional external speaker. You can also use the M33 R2R as a USB DAC on your desktop via USB-C.
Long-Lasting Power
The built-in battery can power the M33 R2R for up to 15.5 hours, or up to 13.5 hours when enjoying balanced playback. For continuous power, you can use the included USB-C cable with an optional power adapter in D.MODE. D.MODE stands for Desktop Mode, which bypasses the internal battery when AC power is connected, extending the lifespan of the M33 R2R's battery.
Durable and High-Quality Display
Access music and settings through the brilliant 1080p 5.5" touchscreen display. The display's front glass is made from 3rd-generation Gorilla Glass for durability, has an oleophobic coating to repel water and fingerprints, and comes with a pre-installed tempered glass screen protector.
