Musical Fidelity M5si

The M5si is a real high end amplifier. At 150wpc, with high current delivery, it will drive virtually any loudspeaker easily.

Internally the amplifier is configured as two independent monoblocks with a separate preamp, but all mounted on one PCB

The amplifier has very low distortion, outstanding noise ratio and an extremely at frequency response. Inputs; phono (mm), 4 line, and USB ’B’ up to 24bit 96kHz.

The M5si produces an extraordinary sweet clear lucid sound. Significantly it was developed after their 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.
