REVIEW & AWARDS

Musical Fidelity M3si Integrated Amplifier –Read More

“The Musical Fidelity M3si, while no spring chicken, justifies its long tenure in the brand’s amplifier portfolio. Simple in design yet full of musical personality, it is a refreshing find in a segment where products often compete on features alone. With a bold delivery that belies its modest power specifications, its sonic performance is competitive at its $1599 MSRP. Thoughtful speaker matching will be required but this care will surely be rewarded with a powerful musical experience. I can warmly recommend the M3si and I am compelled to explore more products from Musical Fidelity in the future.” – Maxwell Geiger

“Partly because the M3si needed proper a run-in and partly because the distributor was in no hurry to collect the amplifier I continued to use it for longer than normal. It turned out to be a fine partner to my system, offering a wide open and beautiful sound. In truth I have not been able to discover any real shortcomings, save to mention that the USB input lags when compared with the line inputs. Maybe Musical Fidelity is still more convinced about the quality of CD players compared to streaming. There is after all an M3 series CD player with its own digital inputs. Those willing to invest in ultimate sound quality using music files will have to look for an external DAC, those with an i device or a PC to play downloaded files can use the M3si as is, it wont let you down. The sleek design contributes to the fun so thumbs up for the chic LEDs, they are bright enough to be seen in sunlight but never beam at you in the evening. Wishes or complaints? Not from me this time. The M3si turned out to be a really nice amp, powerful, pure and able to handle all kinds of music at high or low volume settings. More amplifiers should be this useful and handsome.” –Ren van Es

Musical Fidelity M3i review – Read More

“Summarised in one word, the M3i could only be described as ‘entertaining’. It will replay anything with a sense of excitement and liveliness that is hard not to like. That this punch and timing is coupled to excellent tonality and soundstage and placed in a well-finished and relatively well-specified box, results in a very strong performer at the price point.

The slightly boisterous presentation it can sometimes display with gentler music may not be to everybody’s taste, but many will revel in the sheer enjoyment that the M3i can bring to listening.

If this is the result of a new Musical Fidelity philosophy and an example of what we can expect in the future, then we hope it is one that the firm will follow enthusiastically for some time to come. The M3i is definitely a welcome addition to the fold.” – Ed Selley
