Musical Fidelity M5si Integrated Amplifier Review: A Powerhouse of Sonic Excellence
In this Musical Fidelity M5si Integrated Amplifier review, we explore a remarkable piece of audio engineering that's making waves in the audiophile community. As a reviewer at The Audio Tailor, I've had the pleasure of experiencing numerous high-end amplifiers, but the M5si stands out with its compelling blend of power, precision, and versatility.
Design and Build Quality
The M5si exhibits Musical Fidelity's signature aesthetic - clean lines, robust construction, and minimalist elegance. Available in both silver and black finishes, its substantial 14.6kg weight speaks to the quality of components within. The front panel features a straightforward layout with essential controls that feel satisfyingly tactile.
Performance and Sound Quality
At its heart, the M5si delivers a mighty 150 watts per channel, but raw power isn't everything. The dual monobloc configuration, essentially housing two independent amplifiers and a preamp on a single PCB, contributes to exceptional channel separation and imaging.
The impressive signal-to-noise ratio of 100dB 'A'-weighted ensures your music emerges from a pristinely black background, while the ultra-low THD of <0.010% maintains exceptional clarity across the frequency spectrum.

Connectivity options are comprehensive:
- MM phono input for vinyl enthusiasts
