M2SI - Integrated Amplifier

The M2si is a affordable and puristic audiophile integrated amp, solely designed for maximum musical fidelity.

The M2si integrated amplifier takes our premium-amp technology and applies it to a more affordable price point. Drawing upon the design philosophy and insights gleaned from our mighty TITAN flagship, along with the inclusion of high-end elements such as the robust metal controls, extruded aluminum front panel, and a chassis crafted entirely from metal, the M2si occupies an enviable position for discerning audiophiles seeking an unadulterated high-end amplifier.

 

 

 

 


Fully Discrete Power Amplifier

The M2si delivers 72 watts per channel into 8 ohms and 137 watts into 4 ohms. This means the M2si will drive a wide range of speakers, even power-hungry models. The fully discrete power amp, complemented by its dedicated power supply and generously proportioned toroidal transformer, guarantees reserves for proper peak delivery and a wide dynamic range. Power hungry and difficult speakers are driven with ease. Low impedance dips are managed gracefully and the judiciously rated output devices won‘t faulter under any load.

 


Precision Matched Preamp and PRE/POWER Configuration

The low noise preamp has its own, independent power supply. In effect, this means the M2si offers the performance benefits of a pre/power configuration with the compact convenience of a one-box design. For best low channel volume matching we employ a high quality Burr-Brown stepped attenuator delivering performance way above that of conventional potentiometer designs.


The Musical Fidelity Design-Philosophy

Further flexibility is provided by the M2si‘s carefully considered connectivity, which includes six line-level inputs and switchable home-theatre throughput. We have purposefully decided against a phono input or any digital high-frequency and DAC circuitry. The M2si remains committed to unadulterated sound quality over extraneous features. The introduction of digital high-frequency modules would be at odds with the nuanced performance of the analogue pre and power amplifiers, and the substantial transformer and power amp circuitry could introduce interference to delicate phono signals.

Redefining The Amplifier

With the M2si, our aim was to distill the expertise and design principles honed through our high-end amplifiers, creating an unbeatable package in this price point. Rather than burdening the analog amplifier‘s performance with superfluous features, we opted for a puristic and audiophile-oriented amplifier design that would elicit envy from owners of more costly, feature-loaded integrated amplifiers. With a true Musical Fidelity amplifier, you receive precisely what you desire. An affordable and puristic audiophile integrated amplifier for a lifetime, solely designed for the maximum of musical fidelity.

REVIEW & AWARDS

Musical Fidelity M2si review - Read More

"We play a wide range of music from grand orchestral scores from John Williams to Tracy Chapman’s understated debut set and The XX’s electronica and the Musical Fidelity never disappoints.

It’s a superb all-rounder and one of the best amplifiers we’ve heard below the grand mark. At £799 it splits the difference between two exceptional Rega amplifiers and it's a worthy alternative to either of them – that’s high praise indeed. If you can live with the limited feature count, this one deserves to go on the shortlist." - What Hi-Fi? 

 

Musical Fidelity’s M2si amplifier – weighty yet agile - Read More

"Add in understated but stylish looks and good build quality and you have an amplifier that fully justifies its asking price. Age is but a number they say; ignore it I say. Indeed I can see the M2si forming the core of many excellent systems, whether for Hifi Starters or those further along the path. An Editor’s Choice award is therefore a formality. " - Phil Wright 

 

Musical Fidelity M2si Integrated Amplifier Review - Read More

 "What this is then is an amp that does less to give more. This is a tremendously capable piece of kit that’s a pleasure to live with and demonstrates how a bit of extra heft goes a long way. The M2si is stripped back but it still delivers the essence of Musical Fidelity and for this reason it’s an easy Best Buy. " - Ed Selley 

 

Musical Fidelity M2si and M2Scd - Read More

"Heinz Lichtenegger, best know for the Pro-ject brand and who took over the intellectual property of Musical Fidelity in 2018, wanted to rejuvenate the Musical Fidelity brand, build on its reputation and introduce the well-loved brand to a new generation of consumers. I have seen the brand grow from its infancy in 1982 (when it was of an exciting newcomer) to a mature and varied series of world-class electronics to suit all pockets. The newest models here have certainly benefitted from trickle-down technology and offer a lot of its more expensive siblings’ qualities for the budget-conscious music lover. T

he amp and cd are certainly a good match with each other (of course), but, if used separately, they will still deliver in a well put together and synergistic system." - Ian Ringstead

 

Musical Fidelity M2si Integrated Amplifier Review - Read More

"I’ve thoroughly enjoyed spending time with this Musical Fidelity pairing. The M2si is a fine demonstration of what a reformed brand can produce from the get-go. Modern manufacturing, fresh engineering expertise and no doubt some considerable investment have produced a fine pairing indeed. Highly recommended." 

 

Musical Fidelity M2scd/M2si CD Player/Amplifier - Read More

"The Musical Fidelity M2si amplifier and M2scd CD player are a fine pairing and turn in an excellent performance, especially given their relatively low pricing. These inanimate objects give the impression they enjoy making music and will happily make the most of anything you care to feed them. Their bright nature means careful loudspeaker pairing is wise but, get this right, and they are unlikely not to satisfy. " - Adam Smith & Paul Miller

 

M2scd & M2si - Read More

"As a system, the M2SCD and M2Si worked very well together, and – with appropriate speakers, installed correctly – can deliver music in a manner that does not in any way shame Musical Fidelity’s enviable heritage." - Martin Pipe

 

M2si - Read More

"A powerful yet musical amplifier, that convinces throughout. Useful features und good build quality make this amplifier a „best buy“." - Micheal Lang

 

M2si - Read More

"If you are not currently dependent on digital connectivity, but are looking for an honest
direct, pure analog amplifier, you should listen directly here. It is worth it!
So far, if only the price point isv been between you and a Musical Fidelity amp, it is now
definitely a good time to change that.
" - Jörg Schumacher

 

REVIEW „Hi-Fi Choice“ 01.2019 - Read More

"The M2si hits the test level effortlessly with ample power in reserve on the pleasantly linear volume control. The good news is that the performance is so much more than just a blunt object. While there is a constant feeling of power to the way that it makes music, it never comes at the expense of finesse.  " 

 

 

 REVIEW „Gramophone“ UK, 06.2019 - Read More

"Fed from a very expensive network player, the amplifi er was able to bring out the enhanced presence and information of high resolution fi les and proved capable of very generous bass without any loss of control. Meanwhile the CD player, run through a high-end amplifi er system, showed how persuasively it can play a disc and the levels of music enjoyment it can deliver, whether with a large-scale symphonic work or a delicate solo recording. That it manages to offer so strong a showing suggests that the brand is in very safe hands. "
