Questyle is a brand that is associated with multiple high-end premium products especially desktop DAC and Headphone amplifiers. A few months back they entered the world of portable Hi-Res Audio with their first-ever USB DAC/AMP the Questyle M12. Today, Questyle has released its flagship-grade portable USB DAC/AMP, meet the all-new Questyle M15. Questyle has equipped the M15 with its patented CMA(Current Mode Amplification) technology to design a powerful and clean amp section. Questyle is well-known for its CMA circuits that they implement in almost all of their devices. They offer excellent signal amplification with ultra-low distortion and clean background. The latest M15 is equipped with two CMA modules, and a total of four amplification engines making it ready for its 4.4mm balanced headphone port along with single-ended 3.5mm headphone output.
