FiiO is broadening its selection of R2R devices with the introduction of the M33 R2R, a new music player that occupies the space below the top-tier M27. R2R technology is an age-old method for digital-to-analog conversion, utilizing a collection of precise resistors rather than a contemporary DAC chip. Audiophiles praise this method for its natural and “analog” quality, often delivering music with more clarity and depth compared to many delta-sigma converters.
Core Features of the M33
At the core of the M33 lies a fully differential 24-bit R2R resistor network, which provides the very sound that listeners seek. To make sure the audio is not only pleasing but also robust, FiiO has incorporated a multi-stage TI amplifier capable of producing up to 1100 mW per channel. This power is sufficient for driving both delicate in-ear monitors and demanding over-ear headphones.
Technology and Performance
The M33 is built on reliable technology that promotes seamless performance. With a Snapdragon 680 processor, 8 GB of RAM, and Android 13, streaming applications operate without any hiccups. Users will find 128 GB of internal storage, which can be expanded through microSD, while an XMOS XU316 chip and the DAPS system work together to minimize jitter and noise. A 5.5-inch HD display enhances the user experience. For audio lovers, a parametric 10-band EQ (with Auto EQ support) is ready for adjusting sound to match the headphones in use.
Battery Life and Pricing
The manufacturer claims that the battery life can reach up to 14 hours, which is more than suitable for daily activities. In terms of cost, expected to be around $600/£449, FiiO aims to market the M33 R2R as an affordable choice for those seeking an authentic R2R experience without the need to spend a fortune. The device is anticipated to hit the shelves in the first quarter.
An exciting treat for nostalgia lovers is also set for the first quarter of 2026: the FiiO Retro Box. This speaker can work with the M33 as a source, featuring a display that resembles a digital cassette.
