1. Shanling EM5
EM5 uses a single-chip AK4493EQ as the DAC decoding chip, and uses the classic OP+BUF audio architecture for amplification. Look at the structure of the upper part of the fuselage. As can be seen in the picture, the headphone amplifier part uses TPA6120A2 headphone amplifier, which can provide up to 1620mW output power at 32 ohms and has dual Hi-Res audio verification.
EM5’s operating system is a deeply customized Android that supports a variety of streaming media platforms. However, third-party APPs cannot be installed separately. However, it can support AirPlay and DLNA, and can also directly read NAS files and add local For the server music library, EM5 supports 2.4G/5G dual-band WiFi and wired network port transmission. This depends on actual needs. I used WiFi connection and the transmission was quite stable.
2. M6 Pro 21 version
Shanling M6 Pro 21 version is equipped with USB Type-C interface and three types of audio: 3.5mm single-ended, 2.5mm balanced and 4.4mm balanced. The output interface, in addition to the USB Type-C interface that can realize the USB DAC function, supports bidirectional LDAC/SBC.
It also supports one-way LHDC/aptX HD/aptX Bluetooth encoding format, which means that in addition to Bluetooth headsets, it can also be used as a Bluetooth decoding headphone amplifier. The indicator light above the volume knob can indicate different Bluetooth encoding protocols through lights of different colors.

4. Questyle Audio QP2R
As the amplifier of the "engine" of the sound system, the current mode amplifier based on a fully discrete and special topology can achieve a listening experience that is close to the recording scene, allowing The audience was truly moved. At the same time, with the support of current mode technology, even if the user is using existing headphones or speakers.
The key indicators of parallel current mode amplifiers in audio systems, such as distortion, can reach 0.0002% - 0.0005%, which challenges the current upper limit of physical testing and is dozens to higher than the indicators of ordinary desktop professional-grade equipment. 100 times, you can achieve a truly enjoyable listening experience.
