The left and right audio channels each feature a high- performance, high-efficiency ES9038Q2M DAC to better reproduce every last detail in your music. These DACs allow for decoding support up to 384kHz/DSD256. Audio data is passed through a FiiO-developed 4th-gen FPGA with phase-locked loop technology, which works together with two custom femtosecond crystal oscillators to provide a high-precision and low jitter unified clock source for the entire audio architecture. This is all done in the pursuit of purer sound. The amplifier and op-amp sections of the M11S are independently powered and isolated from each other, ensuring clean and abundant power while resulting in better dynamics. Handle any kind of use cases easily. Under a 32 ohm load, single ended power output is 167mW while balanced power output is at a healthy 670mW–allowing the M11S to better take your breath away when listening to music. Thanks to meticulous and careful design refinement, the M11S has a low noise floor of 1.9μV, 62% lower than the previous generation. Close your eyes and experience the bliss of pure music, unfettered by noise in a pure black background. Access your music in a variety of ways! You can either receive or transmit Bluetooth audio in various formats (with LHDC transmission support for the first time), or you can use DLNA/AirPlay for even more choice. Bluetooth transmission: LDAC/LHDC/aptX HD/aptX/AAC/SBC Bluetooth reception: SBC/AAC/LDAC. With an atmospheric and bold hexagonal structure, the M11S makes a striking impression wherever it goes. The multi-touch 5.0-inch 720p display is perfectly sized for comfort during prolonged usage sessions. On the M11S not only are there the 2.5mm/3.5mm/4.4mm outputs, but there is also even a new balanced line out to be sure you can connect to your music the way you want to.
