Questyle Audio has a reputation among serious audiophiles as a premium audio product brand. They are mostly known for their premium music players and amplifier system. With years of experience in crafting best-in-class audio products, Today Questyle has launched its very first portable USB DAC/AMP, the all-new Questyle M12. It features Questyle’s self-patented “Current Mode” that enables the device to have powerful output while maintaining a low distortion rating of just 0.0003%. Questyle has partnered with ESS Sabre Technologies for the M12, equipping it with a high-performance ES9281AC decoding chip. It enables high-resolution audio signal decoding with PCM support up to 32-Bit/384kHz, DSD up to DSD256, and also MQA decoding. Questyle M12 is available to purchase from HiFiGo with a price tag of 139.99$.

Powerful Driving Force With “Current Mode”:-

Questyle has featured its self-patented “Current Mode” technology in the M12 DAC/AMP. While other similar products in the market are dependent on OPAMPs for the driving force, M12 has ultra-high current output capability and control thanks to this specially developed “Current Mode”. M12 has an output level of up to 2Vrms, even at such high output level, it achieves an ultra-low distortion rating of just 0.0003%.

Intelligent Impedance Detection:-

Questyle M12 features intelligent impedance detection technology. The device intelligently detects the impedance of the connected headphones and adapts the output according to it. For difficult-to-drive high-impedance headphones, M12 will switch the output mode to a high-gain level to provide the required extra power. When driving low-impedance headphones the output level will switch to a low-gain level. M12 switches to high-gain for headphones with impedance above 70 ohms. For anything of 600-ohm impedance or above, M12 switches to line-out mode with an output level of up to 2Vrms.

MQA Decoding Support:-

Questyle M12 supports full MQA decoding. It has an LED indicator that glows in magenta color, denoting that the device is rendering the MQA file. MQA(Master-Quality Authenticated) is a new digital encoding format designed to encapsulate audio streams with extremely high sampling rates in sufficiently small files to make them suitable for network streaming media transmission. The MQA format carries 100% of the information of the original recorded audio signal, and then it cleverly adapts to the audio product you are using and replays these signals with the highest quality that the playback device can achieve.

Hi-Resolution Audio Decoding Support With Sabre DAC Chip:-

Along with MQA decoding support, M12 also decodes high-resolution PCM and DSD audio signals. It supports PCM decoding up to 32-Bit/384kHz and DSD up to DSD256 Natively. All this audio signal decoding is handled by a high-performance ES9281AC DAC chip from ESS Sabre Technologies.

Questyle M12-4

Wide-Range Of Supported Devices:-

Questyle M12 is desgined and developed with multiple device support in mind. It supports any Android device with Android V5.1 or above. It also supports Windows 10 and MAC devices straight out of the box.
