Features:
This is a multifunctional HIFI tube fever preamplifier, which is not only a tube headphone amplifier but also a HIFI 5.0 Bluetooth lossless audio receiver.
Equipped with high-quality Bluetooth 5.0 chip QCC3008, supports APTXs lossless music format.
ESS9023 independent DAC design, I2S digital signal output to ESS9023 decoding, high signal-to-noise ratio, low distortion.
Signal switching adopts relay switching, which is better than a common analog switch.
The electronic bile duct and op-amp can be upgraded, and the amp and op-amp can be changed in design.
Metal aluminum alloy oxidation drawing process, black immersion gold PCB board process, high-temperature resistance, oxidation resistance, and long life.
The ceramic tube socket is durable and has good contact performance.
Independent power supply design with shielding to reduce interference.
