The new Fiio Reference Flagship M27 Digital Audio Player features dual ESS ES9039SPRO 8‑channel DACs, delivering exceptional dynamic range and ultra‑low distortion. Supporting this architecture are dual ES9312 regulators with four independent power supplies, providing isolated power delivery for each differential module. Combined, these systems ensure a quiet, clean background and meticulously precise detailing across all frequency ranges, resulting in transparent, studio‑grade sound reproduction. The FiiO M27 redefines high-resolution portable audio by merging desktop-grade performance with portable versatility. Built on the advanced QCS6490 platform (Snapdragon 778G architecture), this flagship model integrates 8GB RAM and 256GB internal storage, expandable via dual microSD card slots. Its intelligent operating system ensures fluid multitasking and superior UI responsiveness, making it ideal for both professional audio engineers and discerning audiophiles seeking reference-level playback in a mobile form. The new FiiO M27’s HYPER DRIVE amplifier circuit produces a massive 5000mW + 5000mW of output power in Ultra High Gain Mode, matching the performance of full‑size desktop amplifiers. With five selectable hardware gain levels, it effortlessly drives IEMs and high‑impedance over‑ear headphones alike. A dedicated desktop-grade power port enables rapid QC3.0/QC4.0/PD3.0 PPS fast charging, ensuring consistent energy delivery while maintaining safe thermal control during prolonged use. The FiiO M27 is designed as a hybrid “Portable‑Desktop Crossover,” the M27 features coaxial input/output, optical output, 6.35mm headphone output, and Bluetooth 5.4 wireless connectivity supporting aptX Lossless, LDAC, and other advanced codecs. This ensures bit‑perfect audio transmission whether connected to home equipment, streaming devices, or wireless headphones. With QCC5181 lossless Bluetooth processing and XMOS 16‑core XU316 USB decoding, it guarantees superior fidelity across all digital protocols. The new M27 features FiiO’s 6th generation Digital Audio Purification System (DAPS) integrates a new FPGA and dual RIVER femtosecond crystal oscillators to achieve ultra‑low jitter and clock precision. The M27 also introduces the world’s first 31‑band lossless PEQ with AUTO EQ calibration, allowing users to tailor frequency responses to their exact preference or headphone specifications. Preset sound modes and dynamic correction features ensure consistent accuracy and tonal balance in any listening environment. The M27 features a high‑efficiency 3D cooling system combining a graphite vapor chamber and graphene thermal pads maintains optimal heat dissipation. Its closed metal chassis promotes structural rigidity, while dual power sections separate digital and analog currents to minimize interference. Paired with premium components such as NJU72315 volume controllers, OPA2211 op‑amps, and over 70 audiophile‑grade capacitors and resistors, the FiiO M27 delivers sustained, distortion‑free performance even during extended playback sessions.
