Musical Fidelity M5si

Musical Fidelity M5si

The M5si is a true high-end amplifier. With 150wpc, high current delivery, it will easily drive almost any speaker.

Internally, the M5si is configured as two independent monoblocks with a separate preamplifier, but all mounted on one PCB. The technical performance is approximately equivalent to that of the M6si.

The M5si has very low distortion, excellent signal-to-noise ratio, and extremely flat frequency response. Inputs: phono (mm), 4 line-level, and USB ‘B’ up to 24bit 96kHz.

The M5si produces an extraordinarily sweet, clear sound. It was significantly developed following our amazing legendary Nu-Vista 800. Consequently, some of the subtle PCB layout solutions of the Nu-Vista 800 have found their way into the M5si.

When you hear it, we are confident that 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 hint of harshness.
