SANYO STK442-090 customized Pioneer logo PAC014 thick film power amplifier module 80WX2@6Ω brand new and original. Pioneer company customizes the thick film power amplifier circuit with SANYO. All customized products of Pioneer company must undergo careful selection and repeated comparison to determine the circuit structure and sound characteristics. PAC014A is equivalent to SANYO STK442-090, with a recommended operating voltage of ±48V, output power of 80WX2@6Ω, and a distortion level of THD0.2%. This series of products excels in sound details, resolution, vocals, and low-frequency dynamics compared to other series. The module disassembly diagram shows a huge protection chip, and the key parts of the chip are protected with transparent glue. Only high-end products in later stages will do this, which is rare. Buying it is a win.
SANYO STK, commonly known as SANYO thick film, is not a level that ordinary amateur DIY players can achieve, thanks to its tuned sound and high-precision semiconductor process control. Besides better soundstage and resolution, its low-frequency dynamics are significantly stronger, which is the difference between professional athletes and ordinary players! These thick film circuits have always been customized products specifically for major brand audio manufacturers. In the early days, many renowned factories used them to manufacture power amplifiers, such as K+H, Sony, Panasonic, Kenwood, JVC, Sansui, Sharp, Pioneer, and AIWA, almost all of which are Japanese audio manufacturers. They have been used for over two decades, influencing an entire generation, and also representing the sound with a strong imprint of the era that our entire generation heard when we were young. Every time we listen to it, it is unforgettable. The company that SANYO specialized in producing power amplifier modules was later acquired by ON Semiconductor. After the acquisition, it integrated SANYO's traditional craftsmanship with ON's unique design, resulting in even more outstanding products. These products are still adopted by major American companies such as BOSE, and European companies like Genelec!
The actual listening experience of PAC014A thick film is very pleasant, with better sound details, resolution, vocals, and low-frequency dynamics compared to other series.
