D325J HiFi Preamplifier 6J1 Electronic Tube Amplifier TPA3255 Bluetooth 300W High Power Digital Amplifier

Introduction:
- The D325J not only supports RCA and Bluetooth input, but also USB input, making it easy to connect different devices and has strong compatibility.
- The materials used for D325J are full of sincerity, and the RCA socket is gold-plated for greater durability. The machine is designed with the amplifier chip tightly attached to the chassis shell for heat dissipation, which has the advantage of having a larger heat dissipation area and a much better heat dissipation effect than the built-in heat sink. It can work stably for a long time. The FM series large capacity filtering capacitor for Panasonic makes the power supply more stable and has lower ripple. The LPF circuit uses for WIMA capacitors, and the coupling part uses for ELNA advanced capacitors, all of which are high-grade materials. The operational amplifier uses JRC5532, and the electronic tube uses the brand new domestic classic beautiful sound tube 6J1, which operates at a high voltage of 80V to ensure its rich electronic tube flavor. The amplifier chip uses TPA3255, which can output a strong power of 300W per channel and can be used to push various large boxes without any pressure. The QCC3084 Bluetooth module is used for Bluetooth, which supports for LDAC lossless transmission. The PCM5102 is used for Bluetooth decoding, making the sound quality of Bluetooth beautiful for wired transmission. The USB input uses the receiving function of the QCC3084 module, with a bit-rate support of 96K 24BIT and outstanding performance.
