QUESTYLE M15I Portable DAC Headphone Amplifier

The Questyle M15i is a DAC / headphone amplifier featuring an ES9281AC DAC chip with integrated class G headphone amplifier, enabling it to support sampling rates up to PCM 32bit 768kHz and native DSD up to DSD512. This DAC chip is coupled with two CMA (Current Mode Amplification) circuits, i.e. transistors that extend frequency response and reduce distortion (< 0.0003% ) at the M15i's output. Unlike its little brother, the M12i, the M15i has a USB-C input, as well as two headphone outputs: a 3.5mm stereo jack (TRRS) and a balanced 4.4mm headphone jack. Its output power can reach over 2vrms on its balanced output, enabling it to drive a large number of headphones and IEMs available on the market. In addition to the high-end look with transparent glass, a manual gain control is now available on one of the M15i's sides. Coupled with a smartphone, tablet or computer, this little DAC/headphone amplifier is an ideal ally for enjoying your music library or streaming services.
