    Description

    1. The Portable Masterpiece

    The Questyle M18i is the definitive flagship of the M-series mobile DAC/Amp line. Engineered for the most demanding audiophiles, the M18i provides desktop-grade power in a device that fits in your hand. With a fully balanced circuit and enhanced Apple MFi certification, it is the ultimate solution for extracting every drop of detail from high-resolution streaming services like Tidal, Qobuz, and Apple Music.

    2. Key Features & Reference Engineering

    Quad-Engine Current Mode Amplification

    • Reference Purity: The M18i features four independent Current Mode Amplification modules. Unlike traditional voltage-mode amps, this patented technology eliminates the bottleneck of high-frequency distortion, providing a soundstage that is deep, wide, and incredibly natural.

    • Massive Voltage Swing: Designed to drive professional-grade headphones, the M18i offers the energy and headroom required for 300Ω+ studio monitors while maintaining a silent, "black" background for ultra-sensitive IEMs.

    Dual-DAC Flagship Decoding

    • Dual Chip Architecture: Equipped with a Dual-DAC configuration (utilizing flagship ESS Sabre chips), the M18i offers superior channel separation and a massive dynamic range of 130dB+.

    • Ultra-High Resolution: Supports bit-perfect decoding for PCM up to 768kHz, DSD512, and full MQA rendering.

    Intelligent Power & Gain Management

    • Hardware Gain Switch: A dedicated physical switch for High/Low gain allows you to instantly optimize the output for your specific headphones.

    • TOREX Power Management: High-efficiency power management ensures that the M18i delivers maximum performance without draining your smartphone’s battery excessively.
