Vacuum tube and transistor amplifier natural sound field tone dividing system

A vacuum tube and transistor amplifier natural sound field tone dividing system, comprising:

• a front-end circuit for receiving and processing an input signal to thereby generate an audio signal;
• a transistor power amplifying circuit connected to the front-end circuit and adapted to process a low-frequency signal in the audio signal and play the low-frequency signal with a first player;
• and
• a vacuum tube power amplifying circuit connected to the front-end circuit and adapted to process a medium-frequency signal and a high-frequency signal in the audio signal, play the medium-frequency signal with a second player, and play the high-frequency signal with a third player,
• wherein the transistor power amplifying circuit and the vacuum tube power amplifying circuit are independent of each other;
• wherein the vacuum tube power amplifying circuit comprises a high-pass pure vacuum tube power amplifying circuit for generating the medium-frequency signal and the high-frequency signal according to the audio signal and amplifying output power of the medium-frequency signal and the high-frequency signal;
• wherein the vacuum tube power amplifying circuit comprises a passive tone dividing circuit connected between the high-pass pure vacuum tube power amplifying circuit and the third player and adapted to process the high-frequency signal so as to generate a high-pitch signal and provide the high-pitch signal to the third player.
