This HiFi audiophile switch is a selection of excellent Linksys LGS105/108 switches for magic modification


Power without compromise

Traditional magic-modified switches remove the original DC-DC switching power supply and use DC12V DC power supply. But in fact, the main board of the switch adopts DC12V power supply, and then it still needs to be converted into 3.3V and 1.2V low-voltage DC power supply by the DC2DC high-frequency switching voltage regulator chip on the board to supply power to each chip. However, the switching voltage regulator chip on the motherboard will still bring high-frequency switching noise, so this solution cannot completely remove the noise caused by the switching power supply voltage regulator chip. This machine directly uses the 2-level multi-channel low-noise pure DC power supply composed of LM1085 and lt3045 to supply the chip on the motherboard. The power supply noise is as low as uV level, which greatly reduces various noise and interference on the board, which is reflected in the amount of sound information. Without reduction, the background is purer, and the high frequency is more rounded and shiny.


High precision OCXO constant temperature clock

Unlike most businesses in the market who use OCXO from small domestic workshops for grinding, this machine uses a real imported high-precision SC-cut OCXO constant temperature crystal oscillator and low-phase noise PLL circuit to replace the low-end 2-pin crystal oscillator of the original switch. Improve the clock accuracy and reduce the clock jitter, so that the sound details are significantly richer, and the sound field positioning is more accurate.
