I compare FM acoustic 611,811 with MC2 1250 power amp using ADAM studio monitor. MC 2 1250 better thn FM acoustic 611,811 in term of sound quality,MC 2 deliver more transparent , accurate sound tahn FM acoustic
Wonderfull,
i'm always envious of people who find true happiness with more power than the microwave for only $4k.

I've heard MC2 750, it is good amp. It is professional amp, like LabGruppen.
FM amps will reveal it's beauty if the preamp is also FM too.
I have a friend who has unique way for testing good audio sound.
He test it with "Esther" vinyl, took his guitar with him, tune the 440hz tone (with tuning metal fork) and he play the song together with the sound system playing the reproduction. I've witnessed he can achieve exactly the same sound with his FM gears.
The more transparent/accurate reproduction amps will fail this test. The reproduction becomes too accurate than the real guitar sound.

My 2 cents: I've the chance to listen to both the FM Inspiration XS 2 (268/bi-amp 611X) & XS 3 (245/bi-amp F10) system & I can attest that they play or should I say reproduce real music....sounds like the musicians are in your room kind of effect, you don't need to listen loud to "feel" the music. The smaller XS 3 are very good too. And as mentioned it's non-fatigue & enjoyable, listen to one if you can. I've listened to other "hi-end" too but they don't touch your musical soul. Regards
Hello Lumenauw,
I was pleased to see your photos of Manuel Huber. I had seen him at CES in Las Vegas about 10 years ago. I have heard that he has health problems now. I don't know if this report is true.
I am curious to know more about his Inspiration System. In Las Vegas, he complained
unceasingly about the bad room in which his speakers were being shown. Yet, his system is supposed to be sufficiently compensating to overcome room problems. Do the speakers sound best in a small to medium size room? What makes his system so special? Do you know if the speakers have been upgraded since he first demonstrated them years ago? Any comments that occur to you will be greatly appreciated regarding any of the 3 systems. I was told that someone sold his big Genesis speakers to buy the Inspiration System. He misses the large sound stage of the former, but considers the FMA better.
Best regards.
George

MBL, that is a bold statement, because FM Acoustics amplifiers are (despite of the lousy aftersales) at the pinnacle of musicality (if you can say that amplifiers could sound "musical"). Is any of you familiar with JMF Audio of France?

FM Acoustics, ein märchen vom besten
FM Acoustics, 😡
der horror im profi bereich ??
ein angebliches Produkt der superlative !!!
alle probleme mit FM Acoustics Endstufen und Vorstufen sind hausgemachte Konstruktionsfehler, billige ausreden vom Hersteller bezüglich defekte, die beziehen sich natürlich auf alle angeschlossenen Geräte wie Vorstufen oder mixer. Oszillation ist die häufigste ausrede. Die Warheit sieht ganz anders aus. Von Langlebigkeit keine Spur, es gibt auf der ganzen Welt keine einzige FM 600, FM 800 die Ihre versprochene Lebensdauer durchgehalten hätte. Alle heute noch laufenden Geräte dieser Generation verdanken ihr Leben einem Service Techniker aus Deutschland.
Dieser hat sämtliche Konstruktionsfehler gefunden, repariert und die Fehler beseitigt.
Mit Service bei FM Acoustics, der übrigens unter aller sau ist kann niemand etwas anfangen, penetrante Rechnungen für Geräte die definitiv auf konstruktionsfehler des Herstellers gehen, werden auf jeden FM besitzer abgewälzt. FM Acoustics ist niemals schuld an dem gebauten schweizer edelschrott. Im Professionellen bereich werden diese Geräte wohl seit langem nicht mehr genutz da die zuverlässigkeit in keinster weise gewährt ist, lobeshymnen auf dieses Produkt sind absoluter schwachsinn.
Es ist nur Teuer !! sonst nichts

Hi, Soundservice,

And what "konstruktionsfehler" (construction error for those without google translator) they encounter ?
I do not know Fm acoustics but i saw some pics and reverse engineered their schematic from them. I can say its very simple, i think so simple and robust, that it can be very reliable. When I look at the pics of other of their amps, the frontend PCB looks pretty same to me, so I think that the topologies are the same. Even the transistors are the same (2n3440 / 5416), It looks like big quasicomplementary symasym except some minor differences.
When I assume that robust and simple design will lead to a reliable design, I say "their amps can be very reliable", because it cannot be done simpler I think when you are trying to design a classic amp. I think only the trims, for setting bias current and to null DC offset are not very reliable solution. But the bias trim is used correctly, so when the center tap looses its contact after some years, the bias goes down, not up.

Although the design is simple, I like it very much. IMHO I´m quite sure, that if you execute This topology well, you will get extremely good amp. IMHO I´ve some experience now in analog circuitry design. You can go now these days, with all of those patents for free and online, learn it, make some experiments and get an amplifier that is linear as a ruler, but huge and complex, thats not my cup of tea. Complicated structures can be temporarily unstable etc.
Make it sufficiently linear, simple, and carefully look on how the characteristics of your circuitry and your components vary during the signal to be sure, that everything will work fine.
And carefully consider, what the amp have to cope, there are many serious researches. Some of them are quite old, but very good.
There are many other factors, that are usually not tested, and are very overlooked.
There is no magic, rules of physic are still the same, maybe we are just on the wrong way of thinking about amps, because (if you remember monty pythons meaning of life......) people don´t wear enough hats...........

If you look at the FM acoustics newsletters, there are some little lies, perhaps for the sake of being different. But there is quite a lot of, i think, good simple and technical reasoning.

Rey audio JDF is much better than all FM acoustics or all JMF amplifiers (proven history made by legendary sound engineer Tom Hidley)
