Description
xThe new stock SANYO STK4144MK2 chip, this model is an improved version of the STK41X1 classic series, which is a relatively early product. The design at that time was relatively conservative, the materials used were real and strictly tuned. The design output power was 25W + 25W @8 ohms, and the distortion was THD0.4%. It is not the extreme parameters that necessarily represent a good sound, just like many people still like the sound of courage. The parameter performance is not necessarily high, but the sound is mellow and delicate like old wine, the more delicious it is, so this time I chose a more classic retro design, regardless of the sound and appearance, it is the original.
The output power of the STK41X4 series is not too large, and the overall sound quality is between LM1875 and HOOD1969. The sound is mellow and delicate like an old wine. The more you taste, the more delicious it is. It is more suitable for users who like the classic retro sound quality style, especially in the human voice and other aspects. It can bring people a warm and rich listening experience.
