The M5si is a real high-end amplifier. At 150wpc, with high current delivery, it will drive virtually any loudspeaker easily. Internally the M5si is configured as two independent monoblocs with a separate preamp, but all mounted on one PCB and with a technical performance about equal to the M6si.
The M5si has very low distortion, outstanding noise ratio and an extremely flat frequency response. Significantly it was developed after Musical Fidelity’s amazing legendary Nu-Vista 800. Consequently, some of the Nu-Vista 800’s subtle PCB layout solutions have found their way into the M5si. As a result, the M5si projects a deep and wide stereo image with very extended bass and a crystalline top end without a trace of harshness.
