At present, it is used on many audio enthusiasts, with the advantages of good linearity, large dynamic range, and effective utilization of the unique flavor of electronic tubes. On the other hand, it eliminates the need for complex output transformers. The front stage of this machine uses a voltage amplification single ended circuit composed of 6N2 and 6P13, and the final stage uses high-power transistors for simple current amplification, which is called 0dB amplifier, with the aim of capturing the charming sound of electronic tubes The driving ability of transistors. The purpose is to capture the captivating sound of electronic tubes and the driving power of transistors. Due to the high-voltage power supply of the propulsion level electronic tube, A21 has good dynamic performance and an output power of 15W per channel, which is more than enough for use in home environmentsYou can connect various digital devices with Bluetooth, such as mobile phones, tablets, televisions, etc. through Bluetooth!
