M5SI - Integrated Amplifier

The M5si is a sensational integrated amplifier with exceptional power and clarity.

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. 

The M5si has very low distortion, outstanding noise ratio and an extremely flat 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 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.

REVIEW & AWARDS

Musical Fidelity M5si Integrated Strongman - Read More

"The bottom line is that if the requirement is high power, no thrills, tonal mass and soundstage and you are using more modern DACs or streaming DACs elsewhere in the chain already, or using it for vinyl, the M5si comes recommended.

Using my original tag line, this amp justly and credibly stacks up to its reputation as that middle weight Strongman for Audiophiles with everyday speakers that need to be driven really well." - Simon Price

Impression: Musical Fidelity M5si - Read More

"The Musical Fidelity M5si is an integrated amplifier with phono (mm) and a USB input. This very solidly built device is intended for music lovers who want to experience the performance purely realistically. The complete lack of sharpness, the mildly warm tone, the enormous dynamic power, the beautiful midrange and the absence of that annoying (often Japanese) 'whooshing sound' guarantee this. For a lot of extra money you can probably take a step in refinement and detailing, but this Musical Fidelity is absolutely a no-nonsense high-end amplifier that captures the essence of the recording. " - Ruud Jonker

"The master in making music!." - Andreas Günther

HIFIChoice 09/2023

"Extremely clear, clean and crisp, with wide soundstaging and fine depth perspective. This is backed up by a taut, strong bass that’s always there but never overblown. At the opposite end of the frequency spectrum, there’s plenty of detail on show along with a touch of added sweetness." - Nick Tate

Stereo i Kolorowo 04/20

"It’s a perfect sound. The M5si offers a mature, noble color and a subdued, neutral character while maintaining ample power reserves, resulting in excellent dynamics and decent bass. Appropriate proportions are maintained between insight and the naturalness of the sound." - Ludwik Hegel
