Fortunately, I came across the new stock of power amplifier modules produced by Sanyo SANYO in various periods, commonly known as Sanyo thick film. Under the control of the tuned sound and high-precision semiconductor production process, it is not the level that ordinary amateur DIY players can reach. This machine is simply compared with the LM1875 with the same power, and it is found that it is far better than the wave pattern LM1875 produced in various periods, even the most respected by players. In addition to the better sound field and resolution, the low-frequency power is much stronger, which is completely the difference between professional athletes and ordinary players! These thick film circuits have always been customized products for big brand audio manufacturers. In the early days, many famous factories used them to make power amplifiers, such as K+H, Sony SONY, Panasonic PANSONIC, Kenwood KENWOOD, JVC, Sansui, Sharp SHARP, Pioneer PIONEER, Aiwa AIWA, etc. Almost all Japanese audio systems. It is selected by the manufacturer and has been used for more than 20 years. It has affected a whole generation, and it is also the sound that we heard when we were young with a strong brand of the times. Every time it sounds unforgettable.
