Features
  • Single-ended pure class A power amplifier, using FU50 output tube, the overall sound quality is delicate and resistant, full of emotion, low frequency jumping power and high frequency is very good, voltage level adopts Soviet Union 6Ж8, focusing on music and vocals.
  • This product supports Bluetooth 5.0. Low transmission delay, supporting various lossless format transmissions, and the output adds TI's advanced decoding chip PCM5102, which has excellent performance in details, and high and low frequency extensions.
  • High-end Material

All-aluminum alloy structure, precision CNC machining, high temperature resistance, no deformation, no paint.

The transformer is selected from Japan Z11 silicon steel sheet, high quality oxygen-free copper enameled wire, and multi-layer production process to ensure non-destructive output.

Adopting CSR QCC3003 chip, supporting A2DP, AVRCP, HFP, AAC, I2S, etc., adopts 16M SPI FLASH storage chip.

The decoding part uses PCM5102A, which is a 24-bit stereo audio digital-to-analog converter (DAC) with a dynamic range of 112dB, distortion-93db, direct output of 2.1V RMS audio voltage, high frequency without burrs, and low frequency is powerful.
