Specification:
The electronic tube buffer can be regarded as a preamplifier, but its amplification factor is slightly less than 1, and the gain is approximately equal to 0dB.
It can better play the role of impedance matching (increasing input impedance, reducing output impedance, and better driving the rear stage)
The electronic tube buffer can effectively filter out residual digital signals from the audio source, making the sound smooth, warm, soft and durable!
You can also replace the following common types of electronic tubes by yourself: 6N3, 5670, 6H3, etc
