This machine is a reference to the Japanese lead core circuit of E – 360 merger amplifiers BRZHIFI A150 tube HiFi power amplifier, a fever input circuit part is symmetric structure, its characteristic is neutral stability and linear response of various level is more balanced, dynamic big wide frequency response, high SNR, appear a natural voice, because it is a symmetric structure at the same time, It puts forward high requirements for the matching accuracy of components. After making various comparisons in Golden Voice E series, we decided to make this circuit to share with you.
The circuit structure will increase the braking force at 8 ohms /100Wx2 and improve low frequency resolution in this case! The tone is smooth and deep. The voice in the higher range is less harsh and more clear.
The S/N improvement is not only for sound quality, making the sound more dynamic as the value goes up. The sound is more real.
This machine adopts Toshiba K1530/J201 FET power output tube, 2 pairs per sound channel, the circuit is powered by a customized 400W double 45V output power transformer.
