If you've made an investment in some superb speakers you need a superb amplifier to realise their potential.  This is that.

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. Its technical performance is about equal to the M6si.

It produces an extraordinary sweet clear lucid sound. Developed in the wake of Musical Fidelity's legendary Nu-Vista 800, some of the Nu-Vista 800’s subtle PCB layout solutions have found their way into the M5si to great advantage.
