Powerful Amplification With Questyle’s Patented CMA Modules:-

Over the years with their professional expertise, Questyle has designed CMA(current mode amplifiers) for its high-fidelity audio gears. They have used two CMA SiP Modules on the M15 audio circuitry with four total amplification engines. The quadrupole driver amplification circuitry produces a strong powerful output that can drive almost any headphones with ease. It showcases tremendously clean output with low distortion and clean background.

Class-Leading Performance With Flagship Sabre DAC:-

Questyle M15 adopts the flagship ES9281AC DAC chip from Sabre Technologies. The 32-Bit DAC offers best-in-class performance achieving an ultra-low THD+N distortion and high SNR ratings ensuring a supremely clean performance while decoding high-resolution audio signals.

True High-Res Lossless Audio Decoding:-

The Questyle M15 provides an authentic High-res lossless experience with support for 32-Bit/384kHz PCM and native DSD256 decoding. It also supports MQA decoding bringing us closer to the master recording quality at the ease of our smartphone or PC, or tablet.

Dual Headphone Outputs With Powerful Output & Dual Gain Modes:-

Questyle M15 has got two headphone output ports, one single-ended 3.5mm and another fully balanced 4.4mm port. It has two level gain modes, low and high gain. High gain modes will enable the users to use high impedance headphones easily with the M15.

CNC Machined Aluminum Body With LED Indicators:-

Questyle has designed the M15 with a CNC machined aluminum chassis and a transparent front window. Through the transparent window, we can see the entire circuitry inside the M15 and two LED indicators. One light tells us about the active file bitrate while the other indicates the active gain level.

Low-Power Consumption Chipset:-

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.
