Questyle M15 Portable DAC/AMP

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 mazingly powerful yet compact mobile DAC & amp.

Two Independent SiP

This quadruple drive amplification circuitry gives anoutstandingly strong output that can drive almost anyheadphone. Questyle’s Current Mode Amplifiers arecharacterized by their small footprint, low voltage operation,and minimal power consumption. Current amplification has anaturally low impedance, affording the M15 a bandwidth up to1MHz, distortion as low as 0.0003%, and the ability toreproduce every detail hidden deep within any track.

With its four CMA amp circuits, the M15 supports bothunbalanced (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 theconnected headphone, speaker, or HiFi system.
