AKM flagship DAC combination AK4191EQ+AK4499EX Like the Q15 and K9 AKM, the M23 utilizes the flagship AKM DAC combo - AK4191EQ+AK4499EX. It is a new design that totally separates the digital and analogue portions and also features the "DWA ROUTING technology" to further improve the signal-to-noise ratio. These technologies allow for a purer audio background and for higher resolution audio – resulting in a relaxed yet natural sound. Patented desktop mode activated with one click For the first time on FiiO players, the M23 features a switch specifically to toggle desktop mode (D.MODE). When desktop mode is activated, the M23 is completely powered by an external power source. The built-in battery will neither be charged nor discharged, which ensures the M23 can be used as desktop equipment without fear of damaging the battery. Independent Type-C power port - unlimited power On the M23 are two USB Type-C ports, one of which is dedicated to accepting power only (POWER IN). When this dedicated power Type-C port is connected to fast charging, the Super High Gain Mode can be activated for more gain and more output power. In this mode, the output power can reach up to 1000mW + 1000mW per channel, making the M23 better suited for pushing high-impedance headphones. While in this mode, the other Type-C does not consume any power therefor making it suitable to connect the M23 to a phone for use as a USB DAC. New THX AAA 78+ headphone amp design - truly balanced 8-way parallel amplification The THX AAA 78 headphone amplifiers used in M11 Pro and M11 Plus have been widely praised by audiophiles around the world. After several years of continuing to refine the design, we introduced the THX AAA 78+ amplifier architecture in the M23. It allows for greater power output with high fidelity, resulting in powerful sound reproduced with extreme accuracy. High calibre HiFi audio architecture – 4 gain levels The M23 have a high-calibre audio architecture consisting of DAC, I/V, LPF, voltage amplification, and parallel amplification stages. Responsible for handling the I/V and LPF stages are 2 low-noise and high-precision OPA1612 op-amps. The voltage amplification is taken care of by 2 low-noise and high-bandwidth OPA1662 op-amps. Together, these op-amps ensure audio signals are accurately played back at ample power outputs so that a huge variety of headphones and IEMs can work well with the player, which can be further better dialled in thanks to the four levels of gain. High calibre HiFi components – flowing with quality The I/V, LPF, and THX amp parts of the audio circuit utilize a large number of high-precision film resistors. The LPF section specifically employs 8 Panasonic film capacitors. Together, the capacitors ensure a highly detailed and also highly stable sound, as they help to make the left and right channels' output as well as the output of each frequency band more consistent. 4-stage 20-rail power supply for accurate and...
