Questyle M15 Portable USB DAC & Headphone Amplifier News
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.
Questyle M15 adopts a high-performance ES9281AC DAC chip from Sabre Technologies at its decoding core. ES9281AC is a 32-Bit DAC that supports high-resolution PCM and DSD decoding. It also supports MQA rendering for a master-quality studio audio experience right through your smartphones.
For headphone connections, the Questyle M15 has got two output ports, one 3.5mm SE and another 4.4mm balanced port. With the help of Questyle’s patented CMA modules and dual gain modes, the CMA15 will power most headphones and IEMs in the market today. M15 has a solid build with CNC machined aluminum chassis and a transparent front panel. Through the transparent window, we can see the entire circuitry inside the M15 and two LED indicators. One light indicates the active bitrate while the other indicates the active gain mode.
Questyle has featured a low-power consumption chip from TOREX Semiconductor Ltd. There are no over-hearting issues with the M15, and it allows us to listen to our favorite music for longer hours.
