FiiO M25 Portable R2R PRO DAC High Resolution Music Player

The FiiO M25 R2R is a premium portable digital audio player that combines FiiO's latest high-performance player platform with its advanced R2R PRO resistor-ladder DAC technology.

Positioned as the successor to the popular M15S, the M25 R2R sits within FiiO's sub-flagship range and has been developed for listeners looking for a richer, warmer and more natural approach to high-resolution portable audio.

Rather than using the conventional DAC architecture found in the standard M25, the M25 R2R employs FiiO's proprietary R2R PRO conversion technology, giving the two versions distinctly different approaches to sound while retaining the performance and versatility expected from FiiO's latest generation of music players.

Advanced FiiO R2R PRO Conversion

At the heart of the M25 R2R is FiiO's proprietary R2R PRO DAC architecture.

R2R conversion uses a precisely controlled resistor network to reconstruct the analogue audio signal, offering a fundamentally different approach to conventional delta-sigma DAC designs.

FiiO's R2R PRO implementation has been developed for its higher-performance products, with the M25 R2R designed to deliver a rich, smooth and engaging listening experience.

Warm and Natural Sound

FiiO has specifically tuned the M25 R2R for listeners who favour a warmer presentation, with particular emphasis on natural and expressive vocals.

This gives the M25 R2R its own character within the M25 range, making it an appealing choice for those who value musicality and tonal richness alongside excellent detail and resolution.

Powerful Next-Generation Processing

The M25 R2R uses FiiO's latest Qualcomm 6490-series processing platform, placing it alongside FiiO's newest generation of high-performance digital audio players.

The powerful platform provides the responsive operation and processing performance required from a modern premium music player, whether browsing a large local music library or using compatible music services.

Successor to the M15S

The M25 series takes over from the highly regarded FiiO M15S, bringing a new generation of processing and audio technology to FiiO's sub-flagship portable range.

The R2R edition adds another dimension to that formula, offering listeners FiiO's advanced resistor-ladder conversion technology in a premium portable player.

Portable High-End Listening

Designed for demanding headphones and earphones as well as high-quality home listening, the M25 R2R brings FiiO's latest digital audio technology into a versatile portable format.

Roon Ready support further expands its flexibility, allowing the player to integrate with compatible Roon-based music systems as well as serving as a standalone portable music source.
