Musical Fidelity M5si Integrated Amplifier

Brand: Musical Fidelity

The M5si is a high end integrated amplifier, it features a low noise phono stage to allow direct connection of a turntable for vinyl listening. At 150wpc, with high current delivery, it will drive virtually any loudspeaker easily.

An asynchronous USB input has also been included which will connect to computer based home audio and allow full quality playback of digital media, up to and including 24 bits, 96kHz sampling rate. Internally the M5si is configured as two independent monoblocs with a separate preamp, but all mounted on one PCB.

The M5si produces 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.

The M5si will aesthetically match with any future M5s as well as current M3s and M6s series products. Such combinations will yield one of the best high-fidelity systems available at any price.
