Is the poster’s title the Little Prince or the Big Prince? There is only one version of the Little Prince, while the Big Prince has two versions: value version and deluxe version. Judging from the title, it should be the Little Prince. Below I list some parameters of the Little Prince, a Class A HIFI amplifier. Output rated power 80W/8 ohms. Harmonic distortion? Less than 0.08%. Input impedance: 47kΩ, output impedance: 4Ω～8Ω. The signal-to-noise ratio is 100dB (A-weighted), and the weight is 23.5Kg. The input interface is a traditional RCA interface, and the output should be a pure gold-plated copper terminal. The manual is gone.

I started using Feng Zhisheng amplifiers in 1998. The first one was Feng Zhisheng’s Music Princess, which was a level lower than this Little Prince. The second one is the Phoenix AV-999C Century Edition bought in 2009. The reason is that the second AV999 was bought after the Music Princess broke down. The first power amplifier was used for 11 years. In 2009, the left channel began to produce abnormal sound. After the machine warmed up, it became normal. The manufacturer has been contacted and returned to the manufacturer for repair. As for the poster who mentioned that a friend had a problem after using it for a year, I think it is difficult to say because it is impossible to say how long each machine will last before it breaks down. Personally, I think Feng Zhisheng's amplifiers are very well made and are solid.

As for the sound quality, products in this price range (about 2000-2200 yuan) are among the best, and are dark horses among domestic products.
