M15 Reference Mobile Amp & DAC
The new Questyle M15 is our reference mobile amp/dac. It delivers best-in-class fidelity for the ultimate portable audio experience.
The M15 offers world-class digital to analog conversion with the industry's best decoding. You'll be astonished that something so small can process and reproduce such demanding audio formats and deliver such an incredibly low noise floor.
With four of our patented CMA amp engines the M15 will drive the most demanding headphones with ease and control.
The M15 includes both unbalanced and balanced outputs and adjustment for high or low gain settings. Status LEDs indicate: the sample rate, hi-res lossless playback and when the M15 is performing the final unfold of an MQA Core stream. TOREX high-efficiency power management ensures low power consumption, no overheating, longer battery life and longer playback.
The M15 features a metal housing with a transparent cover. It is plug-and-play with no drivers needed and supports most streaming platforms including: Apple Music, Tidal, QQ Music. It fully supports and decodes: ALAC, FLAC, MQA and other lossless formats.
In this complex world, we pursue simplicity.
The era of 5G has brought music streaming from smart devices
fully into the mainstream. As more and more music platforms
launch lossless audio streaming services, mobile hi-res audio has
changed from a neat gimmick into a real and growingly popular
way to enjoy high-fidelity music. However, it’s often impractical
to use traditional HiFi audio equipment with your smartphone
on-the-go, due to size and power consumption. To solve this
problem, the M15 was born: it distills all of Questyle’s expertise
and technologies into an amazingly powerful yet compact
mobile DAC & amp.
Don’t be fooled by its small size. The M15 offers uncompromising
performance and best-in-class fidelity, giving you the ultimate
portable audio experience.
Welcome to the world of truly mobile HiFi.
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 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
Manual gain adjustment
Compatible with even more headphones
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
Complete sonic immersion
Purest sound, anytime, anywhere
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.
When playing audio, the data status indicator will illuminate one
of the following colors:
Treat your senses to true
Green LED indicates the audio sample rate is 48kHz or less.
RED LED indicates hi-res lossless playback.
Magenta LED indicates the M15 is performing the final unfold of
an MQA Core stream.
TOREX high-efficiency power management
Low power consumption, no overheating
Longer battery life, longer playback
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.
