FiiO M33 R2R
Fully Differential 24-Bit R2R Resistor Arrays
The M33 R2R employs fully differential 24-bit R2R resistor arrays, delivering rich analog-like warmth and precision. Each four-channel DAC array contains a total of 192 precision thin-film resistors with 0.1% accuracy and low temperature drift, allowing for detailed, well-balanced, and immersive audio reproduction across headphones of all types. The design preserves the classic R2R sound signature while maintaining clarity and resolution.
Multi-Stage Tl Op-Amps with 1100mW+1100mW Output
The audio circuit features Tl fully differential op-amps in the pre-amplifier stage and quad INA1620 amplifier chips in parallel for the output stage, providing robust 1100mW+1100mW balanced power. This configuration ensures effortless headphone driving, highly controlled dynamics, and a natural, expansive soundstage. Precision electronic volume control further allows detailed, distortion-free listening even at high output levels.
High-End Audiophile Components
M33 R2R integrates premium audio components including Tl Burr-Brown OPA1637 differential op-amps, INA1620 amplifier chips, Rubycon film capacitors, and NJW1195A precision volume controller. These components enhance dynamic range, minimize crosstalk, and ensure natural midrange and smooth treble. High-current MOSFETs and a dedicated power supply system deliver clean and stable energy to all audio stages.
High-Precision Timing & Audio Fidelity
The M33 R2R is equipped with the same ultra-high precision, ultra-low jitter unified clock source found in the flagship M27. It delivers enhanced digital audio processing efficiency and fidelity, providing more precise, natural, and detailed sound reproduction.
Extensive storage Enduringly smooth performance
The M33 R2R's Qualcomm Snapdragon 680 processor, paired with 8GB RAM and 128GB ROM, delivers seamless multitasking and effortless streaming. This generous combination of storage and memory ensures that the player can easily handle future software updates while maintaining stable, durable performance for years of reliable high-resolution audio playback.
