The SK18752 chip is only found in audio products produced in Japan, and is most commonly used by SONY company. Only a small amount is seen in Tenryu DENON, and its performance is no less than SK3875. Due to the excessive hype of SK3875 by merchants in the early stage, many burn enthusiasts are enthusiastic about SK3875. In fact, from a deeper level of analysis, the listening endurance of SK18752 is better than that of SK3875. The static current design of SK18752 is much larger than that of SK3 875, and the listening experience tends to be warmer.
The size of SK18752 is much larger than LM1875, and the packaging size is equivalent to 5200. Due to the lack of official data, after repeated testing, it has been calculated that the rated voltage for the SK18752 chip should be around plus or minus 33V, with an output power 30W@8 Ω. The maximum operating voltage can reach plus or minus 40V (this voltage is not recommended)! ）Its sound characteristics are bright mid to high frequencies and good low-frequency intensity. More pleasing to the ears of good people. It should be that the Japanese did specialized tuning processing when developing these products based on LM1875, coupled with better semiconductor technology. Except for a SONY amplifier that used LM1875 chip, no other Japanese audio products have been found to use the American LM1875 circuit.
This circuit refers to the CG circuit structure, and the sound is very delicate and durable, with an extremely stable midpoint. Our store has received a new batch of SK18752 chips in their original packaging, which are authentic and of high quality.
