Two Independent Cma Sip

The M15 contains two of Questyle’s patented CMA (Current Mode Amplification) SiP modules, for a total of four CMA amp engines. This quadruple drive amplification circuitry gives an outstandingly strong output that can drive almost any headphone. Questyle’s Current Mode Amplifiers are characterized by their small footprint, low voltage operation, and minimal power consumption. Current Mode amplification has a naturally low impedance, affording the M15 a bandwidth up to 1MHz, distortion as low as 0.0003%, and the ability to reproduce every detail hidden deep within any track.

3.5mm TRS/ 4.4mm Trrs Outputs

With its four CMA amp circuits, the M15 supports both unbalanced (3.5mm TRS) and balanced (4.4mm TRRS) outputs. It also has manual gain adjustment via the slider on the side, which makes it easy to choose high/low gain depending on the connected headphone, speaker, or HiFi system.

Impossibly Low Noise Floor

Only a black background can reflect rich color. With its incredibly low noise floor, the M15 allows all the details of your music faithfully ring true. In testing, the M15 was able to achieve a noise floor of -130dB.

ESS ES9281AC Flagship DAC

The M15 features the highly acclaimed ESS ES9281AC flagship DAC, which can handle up to PCM384kHz/32bit and DSD256. It’s almost inconceivable that something as small as the M15 can process and reproduce such demanding audio formats.

Unparalleled Ease Of Use, Plug-And-Play

The M15 supports almost all music streaming platforms worldwide, including Apple Music, Tidal, and QQ Music, among others. It fully supports and decodes ALAC, FLAC, MQA, and other lossless formats. M15 is fully compatible with Android 5.1 and above systems on popular smartphones and tablets. For PC, it supports Mac OS and Windows 10 version 18.3 and above with no additional driver installation required.
