Special note:
The new version has actually been on sale for several months, but I haven't had the time to provide a detailed explanation. Additionally, I invited my good friend JEFF, who is also a senior audio expert, to assist in conducting a very precise sound calibration. The new version has addressed the unreasonable aspects of the original wiring and materials used. After finalizing the design, both the test metrics and auditory experience of the new version have been significantly improved. It has undergone AP testing and surpasses the sound quality of the original model. Audiophiles can purchase it with confidence.

Common Mode Rejection Test
The common mode rejection test diagram is as follows:
The measured result shown in the figure below is a weak signal of 1.61mV with strong noise. After amplification, it becomes a very clean and distortion-free output signal of 831mV.
