The Shangfei SF-1.3 audio power amplifier can be said to be the brainchild of Shangfei designers and many enthusiasts. The amplification circuit has unique craftsmanship, which is different from the design of traditional fever power amplifiers; The sound overcomes both the "hard" of transistor machines and the "soft" of electronic tube machines, making it a unique amplifier with a unique charm.
The signal input is controlled by a lossless relay, the volume is controlled by a Japanese ALPS motor potentiometer, and the 40000 UF large pool and high-power ring transformer provide continuous energy, making the low-frequency full, powerful and elastic. We also use a variety of heating components and single crystal copper wire for sound calibration.
