A great amplifier with a very large 3D sound and a cruel attack !!
Driver my fronts PMC twenty. 26 both 2 channel and cinema.
Like the British Hi-Fi, this sounds great, with great sledgehammer and resolution. MF M6Si has a naturalness and warmth of sound that many other amp lacks. The base is quite lovely, is such a hell of a heaviness in my Kef XQ40 when driven by this. The control of the speaker drivers feel completely when running with a Musical Fidelity M6Si. The whole experience is very physical and it can really lift the more difficult speakers to new levels, compared with smaller amplifier or tired surroundreceivers. I also have an Onkyo TX-NR3030 surround receiver and it is energetic and really powerful but not in the Musical Fidelity Class. Both the preamp and power amp sound better and more right on Musical Fidelityn to me.
MF M6Si is very dynamic, which I like, is the speed of the music I have not heard any other non Musical Fidelity amplifiers with the same drive and punch in the face. And then I also Hegel H160 (Hegeln feels airier, more finesse, but not as powerful and H160 have less ground moves), Bladelius Thor MKIII (feels as powerful but Bladelius is more distinctive in the sound of good and evil, M6Si is more forgiving against inferior sources and materials) and Devialet 200 to compare with. Have never been disappointed in MF. And I had 3st now A308, M6i and M6Si. The phonetic difference from the older M6i is minimal according to me. But M6Si the MM / MC phono input.
16.6kg, built-in USB DAC and HT Direct input for connecting directly to the final stages of the surround receiver.
Has three real complaints. The first is that it is difficult to see how the volume pot stand, a small notch is not visible in the distance, but there is anyway little clearer than the M6i. Former MF models have been clearer indication. But this can be solved with a small sticker or something. The second is the built-in USB DAC is right dull sound, and also lacks optical and coax, this is Hegel H160s built DAC light years ahead. A better DACs than the built-in M6Si going to find a few thousand both new and used. The third is remote, MF's usual dreary and additionally direction-sensitive and with a slight delay when you increase / decrease.
According HiFi and Music effektkub gives 259 watts into 8 ohms, 424 watts into 4 ohms, 548 watts into 2 ohms and 268 watts 1 ohm. Compared to M6i bit weaker in 8 and 4 ohms but a little more power in 2 and 1 ohm which is good for difficult speakers.
Had this play for a while now. Really funny. Bass and very airy sound. Current Strong is just the beginning. However, the built-in DAC no picnic. Therefore, I removed two stars.
The design is however very stylish, timeless design. Very simple and easy to use. Build quality world class!
Right out of the box it plays really nice. Update my review when it got to record itself.
Edit: Now I have lived with my M6si a while and I'm really pleased. Large soundstage, access details, but they are trying and last but not least: POWERFUL. More digital inputs had not done evil, but otherwise a really, really good amplifier that is also very good looking.
