Description
EXCELLENT PERFORMANCE WITH FLAGSHIP SABRE DAC
Questyle M15 comes with a flagship ES9281AC DAC chip from ESS Sabre Technologies. A 32-bit flagship DAC chip that decodes high-resolution audio signals with excellent performance. The M15 offers best-in-class audio performance with a clean background and ultra-low distortion at the output!
QUESTYLE’S PATENTED CMA MODULES
Questyle has a patented Current Mode Amplification Circuit that they implement in most of their high-end HiFi devices. This latest USB DAC/AMP utilizes two CMA SiP modules with four amplification engineers. CMA (Current Mode Amplifier) produces a powerful output thrust, making the compact M15 a powerful beast. The device is capable of charging most headphones on the market.
3.5MM TRS / 4.4MM TRRS OUTPUTS
The M15 supports both unbalanced (3.5mm TRS) and balanced (4.4mm TRRS) outputs. It also has a slider on the side that allows for manual gain adjustment, so you can choose high or low gain depending on your connected headphone, speaker, or HiFi system.
HIGH-RES PCM, DSD, AND MQA SIGNAL SUPPORT
Questyle M15 provides its users with a high-resolution experience that is compact and powerful. The M15 supports native 32-Bit/384kHz PCM decoding, as well as DSD256 decoding for high-resolution PCM. MQA Streams are also supported, so users can enjoy the master-quality studio-level sound.
TOREX HIGH-EFFICIENCY POWER MANAGEMENT
The M15 is equipped with TOREX High-Efficiency Power Management, which can result in low power consumption, no overheating, longer battery life, and a longer playback time.
M15 CONNECTS YOU TO THE STREAMING ERA
The M15 supports almost all music streaming platforms, including Apple Music, Tidal, and QQ Music. This program supports and decodes ALAC, FLAC, MQA, and other lossless audio formats.
CNC MACHINED ALUMINIUM BODY
M15 has a CNC machined aluminum chassis and a transparent front window. Through the transparent window, we can see the entire circuitry inside the M15, as well as two LED indicators. There are two lights, one indicating the bitrate of the active file, the other showing the gain level of the active file.
