Questyle M15
Portable USB C to 3.5mm/4.4mm DAC and Headphone Amplifier

--
Descriptions:

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.

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.

When playing audio, the data status indicator will illuminate one of the following colors:
Green: indicates the audio sample rate is 48kHz or less.
Red: indicates hi-res lossless playback.(Hi-res lossless refers to PCM 88.2kHz~384 kHz, or DSD64~DSD256.)
Magenta: indicates the M15 is performing the final unfold of an MQA Core stream

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.
