Is it better to change the optical fiber for Prado audio or the original car line?

Optical fiber audio line is good. In terms of sound transmission, optical fiber audio cable is a digital signal transmission, which can better separate sound, while 3.5mm audio cable is an analog signal transmission, and digital-to-analog conversion is carried out through a built-in sound card. The sound effect will be slightly worse than optical fiber transmission, and the signal transmission speed will be slightly slower than optical fiber transmission. Therefore, the use of 3.5mm audio cable will occasionally cause the sound and picture to be out of sync.
