(released on July 1th 2022 in Japan)

Description

  • Extra large dynamic and rich detail

    • By including two current mode amplifier "engines" in one current mode amplifier module, a total of four current mode amplifier "engines" are installed, resulting in more powerful output and driving power. Current-mode amplifiers are characterized by small size, low voltage, and low power consumption.
      Meanwhile, you get a bandwidth of up to 1MHz and distortion as low as 0.0003%, allowing you to capture details hidden deep in the sound.

    3.5mm, 4.4mm output, manual gain adjustment, compatible with more earphones and devices

    • Equipped with a quadruple driving force current mode amplifier module, it supports 3.5mm stereo and 4.4m balanced output, and can be adjusted with a manual gain bar.

    Super strong decoding performance, carefully selected ESS9281AC chip, mastering-grade recording restoration

    • Equipped with the ESS flagship level USB DAC chip "ES9281AC", it supports PCM384kHz/32bit and DSD256, and achieves high fidelity in a small body size.

    Ultra-low noise floor brings you an immersive sound experience

    • A low enough noise floor allows you to capture the deepest details of the sound, giving you a taste of true fidelity. In the Questyle lab test environment, the M15 achieved an ultra-low noise floor of -130dB.

      TOREX High Efficiency Power Management
