Descriere
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.
M2si In Brief
Amplifier
- High-end circuitry inspired by TITAN
- Fully discrete transistor based Class A/B power amp design
- Drives power hungry speakers with ease and gracefully manages low impedance dips
- 72W/8 Ohm & 137W/4 Ohm output power
- Extreme power reserves for proper peak power delivery and wide dynamic range
- Pure sound quality instead of features:
- – No digital circuitry: no digital high-frequency modules built in
- – No phono stage: huge transformer and power amp circuitry will not interfere with low level phono signals
- HT-input: bypassed preamp-stage allows connecting home-theater processors to use your M2si as ultimate L/R channel amp
Preamplifier
- Low noise design for best THD and signal integrity at low as well as high levels
- High quality Burr-Brown stepped attenuator for better channel matching than conventional potentiometer designs
- Pre Out for bi-amping with M6sPRX or active subwoofer connection
Power Supply
- Generously rated 280VA toroidal transformer
- Independent power supplies for preamp and poweramp
- Output devices, and power supply generously rated to provide peaks even into difficult to drive speakers
Mechanical Construction
- Uncompromising metal work in typical Musical Fidelity tradtion
- Heavy front panel milled from extruded aluminium profiles
- Clean, stunning and indestructable metal exterior protects against electromagnetical interference

Explicatii in ceea ce priveste rodajul echipamentelor, cat si al cablurilor, asezarea optima a echipamentelor in camera de auditie, importanta acusticii camerei si nu in ultimul rand sistemul de alimentare a intregului echipament:
PENTRU BOXE:
- Pentru performante optime este necesara pozitionarea boxelor la o distanta de minim 30-40cm de peretele din spate pentru boxele cu bass-reflex in spate, pentru cele cu bass-reflex in fata, recomandam pozitionarea la o distanta de 10-20cm fata de peretele din spate, dar totodata la o distanta de cel putin 50cm fata de peretii laterali. Tineti cont de faptul ca orice piesa de mobilier din incapere, joaca rol de absorbtie fonica, dar si de difuzie fonica daca acestea din urma sunt din materiale ceramica sau oglinzi, geamuri sau alt material reflectorizant. In acest sens, gasiti pe blogul nostru, multiple articole care va pot ajuta
- Boxele vor ajunge sa functioneze in parametrii recomandati de producator, dupa minim 50 de ore (ideal 100 ore) de functionare la volum mediu. In aceasta perioada de timp, de “rodaj a boxelor”, sunetul va fi la inceput mai artificial, bass-ul nu va fi inca controlat, inaltele rigide iar vocile usor retinute, pe masura ce boxele vor functiona, veti remarca cum bas-ul devine mai controlat, mai prezent si mai voluminos, vocile si sunetele medii devin naturale si mai echilibrate, iar inaltele devin rafinate si detaliate. Exista boxe care necesita un „rodaj” mai amplu de minim 300 de ore mai ales in cazul celor care au difuzoare de kevlar, carbon sau alte materiale de acest tip. Boxele care se „rodeaza” cel mai repede sunt cele care au difuzoare de celuloza.

PENTRU AMPLIFICATOARE, DAC-URI, PREAMPLIFICATOARE, RECEIVER STEREO & HOME CINEMA, SURSE DIGITALE AUDIO-VIDEO:
- Pentru performante optime este necesar „rodarea” echipamentului, In functie de complexitatea componentelor din aparatul dumneavoastra acesta poate dura intre 30-200 ore.
- Rodajul se face la volum minim, fiind astfel suficient faptul ca acesta este alimentat corect conform manualului de utilizare la 220-230 Volti si trece semnal audio sau video dupa caz prin el.
- Echipamentul supus „rodajului” va ajunge sa functioneze in parametrii recomandati de producator, dupa perioada mai sus mentionata. In aceasta perioada de timp, de “rodaj”, sunetul va fi la inceput ceva mai artificial, bass-ul nu va fi inca controlat, inaltele rigide iar vocile usor retinute, pe masura ce echipamentul va functiona, veti remarca cum bas-ul devine mai controlat, mai prezent si mai voluminos, vocile si sunetele medii devin naturale si mai echilibrate, iar inaltele devin rafinate si detaliate.
- In ceea ce priveste echipamentul video precum videoproiector, TV, media player, blueray player, necesita un "rodaj" de cel putin 50 de ore. Lipsa acestuia nu va poate oferi maxim de performanta. "Rodajul" se efectueaza prin simpla utilizare a acestuia, intr-un mod conform specificatiilor mentionate de producator.
PENTRU CABLURI:
- Pentru performante optime este necesara „rodarea” cablurilor, In functie de complexitatea conductorului folosit, cat si geometriei acestuia, „rodajul” poate dura intre 30-100 ore.
- Rodajul se face la volum minim, fiind astfel suficient faptul ca va trece semnal audio sau video dupa caz prin el.
- Cablul supus „rodajului” va ajunge sa functioneze in parametrii recomandati de producator, dupa perioada mai sus mentionata. In aceasta perioada de timp, de “rodaj”, sunetul va fi la inceput ceva mai artificial, pe masura ce cablul va functiona, veti remarca cum bas-ul devine mai controlat, mai prezent si mai voluminos, vocile si sunetele medii devin naturale si mai echilibrate, iar inaltele devin rafinate si detaliate.
