Questyle M15i Purple and Blue: Meet the New Versions of the Portable DAC/Amp

The Questyle M15i Purple and Blue versions were officially released in the Chinese market last Sunday (4). According to the manufacturer, these are special editions with “special tuning” achieved through the use of different hardware components in the M15i. The goal is to deliver an even better experience for specific music genres such as electronic music, ACG, jazz, and blues.

What is the difference between the standard Questyle M15i and the Purple and Blue versions?

According to the company, the Purple version of the M15i features sound tuning aimed at electronic music, hip-hop, rap, and other similar genres. Its purpose is to provide greater immersion and a more intense rhythm by optimizing transient response.

The Blue version of the M15i is designed for jazz and blues, offering a more intimate soundstage and a stronger live-sound sensation. Here, the focus is on midrange warmth and high-frequency harmonic layering.
