Features:
Use imported 5654 tube
The main filter capacitor adopts the original imported 1000UF/50V
The resistors are high-precision chip resistors to ensure a good signal-to-noise ratio of the whole machine.
PCB adopts a 1.6mm thick double-sided board, 2.0 oz copper thickness, and a full tinning process to ensure the good passing performance of large and small currents.
The input and output use gold-plated RCA lotu seat, durable and beautiful.
The board wiring is reasonable, beautiful, and low noise
Bluetooth uses Qualcomms QCC3031 module to support sbc/aac
Bluetooth DAC uses PCM5102 to decode independently
