Your Kef sensitivity is 88 dB, hence technically, I believe even the CA851a can drive it easily at 120 wpc. My ProAc D18 has the same sensitivity and I have experienced the benefit stepping up from 50 wpc (MF XA1) to 70 wpc (MF M3) to 200 wpc (M6i). I do believe more will give better results but the best way is still to demo your speakers with the amp of your choice.. Good luck.

Hi El Hefe,
I am late for this thread, but I need help on my new purchase.
I am Planing to replace my Parasound Combo (P7+A23) for a Integrated Amplifier to drive my KEF R300.
I narrowed the options for M6i or Cambridge 851a.
The Cambridge is a better buy ($$) , but some folks said taht the R300 requires more power.
Also, will the replacement l be a side step???
Any help will be wellcome
Antonio Hi I have listened to the kef r500 and the r700 on the end of the M6i and if the r700s had not been so tall I would have bought the kefs as they really whent well very with the M6i loads of power and control massive sound stage it will make you listen again to all of your music good luck get a home dem if you can

I think you should consider 2 other good and powerful options and for my opnion much better than the MF M6i and CA 851 :
ROTEL RC-1580 (pre) + ROTEL RB-1582 (power)
AUDIOLAB 8200Q (pre) + AUDIOLAB 8200M ( monoblocks )
Hi Fi : Proac Studio 140MK2 - Rotel RC1580 [PRE AMP] - Rotel RB1582 [POWER AMP] -Rotel RCD1520 [CDP] Cables : Tellurium Q Black speaker cables- Tellurium Q Ultra Black RCA interconnects - WireWorld Stratus 7 power conditioning cords

I have been using a M6i integrated in my system for around a month. Previously I was using a Primare I30 amp,
Although the Primare was a very good amp, the sound difference from the M6i is substantial.
Tighter more controlled base
Effortless response to transients
Brings out not only more detail from the music, but the timbre of individual instruments is more defined.
Loud, complex orchesteral pieces appear to be made up of different instruments rather amalgomating into a grouped noise.
My system comprises of - Spendor D7 Speakers, Cyrus XPQX streamer with power supply and Musical Fidelity M6i amp.
Sorry but I have to disagree with most of the comments here. I had been using around 8-10 different amplifiers from different price range and this is how MF M6i compares to others:
The sound of the MF M6i:
-Elevation in the low,mid and high frequencies ( so the freq. response is a kind of sinusoid, NOT flat)
-Very soft and warm low end (defenitely NOT tight and NOT controlled)
These are the major issues.
-Punchy,dynamic,detailed. But all these good things cannot be enjoyed in the shadow of the issues)
I tried the M6i with Dynaudio focus 220, B&W 602 S3,Meridian G08 cdplayer,Krell 350a cd player
If you are after tight and controlled bass try a Krell or Dussun or other class A type amp.
I cannot recommend the M6i to anyone who loves rock/metal music.
Thanks for reading
That's a very interesting input.
Apart from Krell and Dussun, which other integrated amps do you think are good for Rock/Metal?
And by the way, does anyone here strongly desagree with Akos re M6i being unsuitable for Rock/Metal?
Perhaps the Lavardin integrated amps which I had the pleasure to listen to at the Bristol show not long ago. I know it's a matter of personal taste/subjective, I do not state only controlled bass is good enough to handle rock music but it is much more lifelike than listening a rock concert on a softish/warmish amp like the M6i. I use the well recorded Police- Argentina concert as a reference point. It's a strong one, is'nt it?

]I disagree with Akos my music taste is Rock. Blues. Metal. Prog Rock Maybe speakers cdp and room acoustics have played a part in Akos's dislike of the M6i my M6i delivers tight controled bass massive sound stage and a punch which would knock out tyson .by the way I listen to acoustic music. classical music in fact I listen to all sorts and the M6i delivers it spot on.
Agree with toyota man AND akos... Cannot really generalise the M6i will match in all set up especially the speakers. I know for sure it did not match my previous EPOS M12.2 bookshelf speaker...but for sure ProAc, ATC and Spendor usually match well. Rock or metal music.... No issues for the M6i to cope with fast beating drums nor any heavy guitar riffs....but again...depends on the speakers too...
Thank you guys.
It's just that I had a terrible experience with Rotels (RA-1570&RB-1582), and I really don't want to go through any such disaster anymore. Since I can't compare different amps (well, now I can, since I am in London area, but there are no stores with Heco The Statement for demo, so no point in making auditions with other speakers), I was wondering about any good alternatives for heavier musical genres.
People say Naim is good, but they don't have power enough (Nait XS for example) for my Hecos.
Now Akos says M6i lacks the bass sharpness needed for Rock/Metal..
I think you are missing the point here, no punt intended. Akos have tried M6i with the likes of Dynaudio, B&W ... Toyotaman is using it with Spendor... I have used it with EPOS, Mission and now ProAc... Toyota Man and I are very satisified with the M6i to deliver the bass, the mids and high of vocals and guitar riffs of rock and metal... All of us tried the M6i with different speakers...
Naim matches well with Dynaudio and ProAc as well.
If you are not able to demo the M6i with your speakers, try to find a retailer who stocks the M6i and the range of speakers above. All of them will give different results.
What was so bad with the Rotels RA-1570 & RB-1582 ?
The M6i is beautiful and with strong built quality . I had been using it for a year before it became obvious that (with my system) I got the feeling as if it sounded like a hidden LOUDNESS buttom was constantly ON. I mean loads of bass and highs but that bass was overhanging,lasted too long,never stopped where and when it should have...some would describe this as SLOW BASS. Your room acoustis and speaker design will only make a little difference. With the same equipment and room other amps produced much tighter and controlled bass. I found that silver interconnect made a slight difference but .....it still had to go. Anyway, it is a matter of taste and somone may think that BIG bass equals good bass control but I disagree here. I know that is the preamp section of the M6i that is to blame here as I tried with Benchmark DAC PRE -connected to M6i power amp directly and it sounded fantastic with tight and accurate bass.
