Track introduction:
"Diabolus in Musica-La Campanella", Performed by the famous Italian violin master Accardo. Any violin fan should not miss this "Devil's Sound". According to legend, with the help of the devil, people can achieve the greatest pleasure. Listening to this disc attentively, you will know how irresistible the temptation is like selling your soul to the devil, and you have to buy it and go home. The song "La Campanella" demonstrates the master's skillful skills, including continuous bow jumping, sliding bows, bow pauses, double overtones, double vibrato, left-hand plucking and other ultra-difficult skills. These techniques are a major test for the resolution and large dynamic performance capabilities of the playback equipment, so they have become common tracks for our testing.

Faye Wong's "Sky-Unplugged", this album released in 1994, is a classic work of Faye Wong. Feifan's sound, which is quite charming but full of fresh feeling, is definitely a strong medicine for fever. Unplugged in this song means "unplugged", which means that this song is completely composed of self-sounding orchestral instruments and percussion instruments with vocal production, and has not been contaminated by rock poisons such as bass and electric piano. This is exactly what it means. It fits the characteristics of Faye Wong’s voice: very charming. If you want to play this song well, the resolution of the entire playback system and the fullness of the mid-low frequency will be severely tested, so it became our gold audition disc for pop music.

Maxim's "Exodus", Maxim's piano music is somewhat similar to Richard Clayderman's playing method, It is to make "classical music popular". By inserting extremely rhythmic accompaniment and various harmonies and mixes, he made the piano a popular art, no longer rigid and stagnant, and made it acceptable to everyone. "Exodus" is a bit biased toward religious music. The piano and violin complement each other in a grand and realistic way, which adds to the feeling of surprise. So, listen carefully to the lingering sound of the piano.
