About the item: What Type of Amplifier Is This? ZK-152H is a power amplifier composed of a tube pre-amplifier and a class AB power amplifier chip. Its characteristic lies in the combination of the electron tube as the front stage and the class AB power amplifier chip as the rear level, neutralizing the advantages and disadvantages of the class A power method and the class AB power amplifier. This method allows users who are all in pursuit of music quality to obtain sound quality improvements at a low price. What Chip Does This Tube Amplifier Use? This power amplifier uses a 6J1 tube, and it uses TDA7377 Class AB power amplifier chip. The output of its sound quality has a certain gap to the Class A power amplifier, but for the Class D power amplifier of the same level, the ZK-152H is essentially superior. Especially in terms of vocals, ZK-152H does not have a strong "digital" taste, but it sounds more "temperature and soft" What Is The Output Power of This AMP? The TDA7377 chip in this AMP converts the total output power of the AMP to 35W through a bridge connection. How Many Watt Speakers Are Suitable to Connect to It? We recommend using speakers within 150w, or the size of the speakers should not exceed 6 inches.
