"The M5si is a real high end amplifier. At 150wpc, with high current delivery, it will drive virtually any loudspeaker easily. The M5si has very low distortion, outstanding noise ratio and an extremely flat frequency response, producing an extraordinary sweet clear lucid sound. Significantly it was developed after our amazing legendary Nu-Vista 800. Consequently some of the Nu-Vista 800’s subtle pcb layout solutions have found their way into the M5si. When you hear it we are sure you will understand the relationship between the two. The M5si projects a deep and wide stereo image with very extended bass and a crystalline top end without a trace of harshness." - Musical Fidelity
