Responsive and Powerful! | Moonriver 404 Reference review in HiFi Review magazine by Chen Haichuan
“Drum Improvisation is crisp, refreshing and energetic with contrast between big and small percussion instruments The soundstage and front-to-back layers are clear. It also makes me think that Model 404 Reference is class AB but it sounds like a class A with higher bias, so it is not only that has delicate tone, but it is also vigorous and lively It also has heart, power and speed when playing the drums.”
