Would This Amp Be Worth The Cost?


Opinions please.
Amp for Sonus Faber Olympica III speakers.

Looking at this amp  Musical Fidelity M8s-500S Power Amplifier
Info https://www.musicalfidelity.com/products/m8series/m8-500s

Replace my Classe Sigma Amp2.
Info

AMP2

FREQUENCY RESPONSE:

10 Hz – 20 kHz, -1dB into 4 Ohms

OUTPUT POWER:

200W rms into 8 Ohms, 400W rms into 4 Ohms

HARMONIC DISTORTION:

<0.018% @ 1 kHz Balanced Input

INTERMODULATION DISTORTION:

>80 dB below Fundamental into 8 Ohms Balanced

SIGNAL TO NOISE RATIO:

-100 dB at Peak Output into 8 Ohms (AES17)

Would there be improvement? Worth the cost? 
Thanks

Why would you buy that amplifier the Coda #8 power amplifier is the best sounding Amplifier I have heard under $10 k and retail $6200 
can be bought for $5500 delivered .it is a steal  and 3 power choices and amount of 1st watts into pure class A . match the build quality not even close and Made in USA 
for over 35 years .  Do a bit of research ,and reviews .
@greywolf, 

Can you tell us about the rest of your system?  What preamplifier are you using?  What are you listening habits? How loud do you like to listen?  What is it about the Classe that you like/don't like and/or reason for replacement? 

From what I can tell, that Musical Fidelity is a ~$4k-$5k amp.  Is that a good budget for you?  


Einstein’s theory of relativity is about 100 years old. So I guess it must be rubbish. Being something so old and all. HVAC
@greywolf,
Your have received some wise counsel in response to your post and I hope you give it some thought and consideration. When I first ventured into the audio world I was introduced to a magazine quite popular at that time called Stereo Review. The featured audio reviewer was the late Julian Hirsch.

I respected his background as an electrical engineer and initially gave credence to his opinions, which essentially was that most amplifiers measure well and subsequently will pretty much all sound the same. As I gained listening experience and exposure to more audio equipment I realized that Mr. Hirsch with all due respect was just plain wrong.

I could easily hear obvious and distinct differences between amplifiers and other audio components. I recognize that everyone has their unique experiences and perspective. However I strongly disagree with probably well meaning advice that 400.00 amplifiers are all that’s required and anything above and beyond is simply preferred distortion.

Go out and listen first hand for yourself to a variety of different amplifiers and see what you find. Measurements are useful to a point but will not reveal how a component or product is going to sound. You have to judge with actual listening encounters.
Best of luck to you.

The only way to know is to plug it into your system and listen.  Specs are meaningless on a printed page
the ’all amps with the same power sound the same’ bs got a lift when alan shaw of harbeth openly pushed that line of thinking in his manufacturers’ user group, which he runs with a heavy hand and shouts down points of view contrary to his own

anyone with good ears and some experience in this pursuit knows that this is total nonsense, purely self serving from a guy who sells pricey speakers - even more hilarious to then see him admit he 'just happens to use' a hegel h360/h390 in his in-house speaker testing, listening and at hifi shows... 🤣🤣🤣
So I guess it’s time to sell all of our amps and buy Chinese $400.00 amps. They don’t make a difference? Nor does anything else. Lamp cord for speakers, interconnects, power. My world just got a whole lot cheaper...

To the OP, Musical Fidelity makes some good products for the $$, best thing to do is audition... really, it’s the only thing to do. Then choose which you prefer. 
Any particular choice of amplifier above a basic good design (about $400 seems to be enough) would be justified only if you deliberately seek some distortion type of your choice.  

Check it out: Totally admits there are differences, but only if you deliberately want them, and defines all the differences as distortion. Intellectual insanity. Pure blather. But there's loads more where this came from.  

Personally, I think we could use a few more people like this. Really high quality components are hard enough to find as it is. Their prices are high in part because so many people want them. Wait times on Tekton and Decware are in the months, to pushing half a year. The last thing we need is more talented discriminating quality-oriented listeners competing for them. The more noobs buying Bose the better. Let's hear it for 'em! 

Louder! I can't hear you! Well no actually I can. But they can't. Hard of hearing. Obviously.

"...You should listen to what your ears are telling you. If it’s not something different you might need to abandon this hobby and try needlepoint..."

The guys that believe all amps sound the same, if not driven into distortion, have either never heard a good system, or have never bought a premium amp, or believe all audiophile products are made just to extort money from the unsuspecting. Frankly I feel sorry for them because their systems must really suck.
The Musical Fidelity represents a strong value.  They are made in Taiwan (at least for now, production seems to be migrating to Canor in Slovakia) and as a result are a lot less expensive than many made in US/UK/Germany/Japan products.  Very good sounding.  Oodles of power and although a touch forward, probably less forward than that Classe.  It should be more refined as well.  You would spend a lot more and get less power (though a touch more refinement) out of a Chord Ultima 5.  It should be an excellent fit for those speakers.  
Incidentally I am a dealer for both Chord and Musical Fidelity.  I checked and that amp is in-stock at the distributor in Black.  
Seems like there are loads of ABX listening tests (Carver Challenge, etc) which tell us there is no audible difference between any amps which deliver sound at your top listening levels within their design limits. Any particular choice of amplifier above a basic good design (about $400 seems to be enough)

Is what they are telling you? Do you really believe that s$&t?

You should listen to what your ears are telling you. If it's not something different you might need to abandon this hobby and try needlepoint.


op

musical fidelity are good performing, well built amps that represent good value

i have found their sonic character to be extended, lively, solid state state sound, with little harshness

other (largely more expensive) brands may present the music with somewhat more richness

older classe’s (class a/b amps that put the brand on the map years ago) would sound warmer more dimensional than modern musical fidelity’s... i have not heard the specific classe class d amps you have...
I'm a big fan of Musical Fidelity's products. However you have what I think is a decent amp. There may be a change by swapping amps but the change might be very small and only at the frequency extremes. If I was looking for a change I would be looking at the pre-amp. What pre-amp and source are you using? 
Yea, about any amp above 400.00 will work. LOL That is 1990s tech, along with the flat earthers (fuse and cables make no difference crowd).

When folks quote "Blind test", Including the name "Carver", BS!!

It’s real obvious you don’t know too much about Bob Carver or you wouldn’t SAY your quoting him. That guy is his own man, and changed with the times just like everyone else, who is still in business.

Either you change, or start working for someone else.. The audiophile community would have put him out of business along with ALL the other Amp companies that have gone by the wayside.. That guy pushed a lot of cool ideas, BUT was able to tell the difference in sound quality, by changing a 50 cent part. Even Mcintosh changed the stupid policy of "Cable don’t matter" 20+ years ago.. BUT people quote from the 60-70s. KEEP UP!!!

No good treatment for cancer back then either, there sure are some good treatment now... Which articles do you read? Mustard gas treatment with radiation, or todays options.. I know what I would chose...

His idea that it doesn’t cost a fortune to voice or change the voicing of a product is his greatest asset, THAT is what Bob Carver was known for.

BTW so was Mr Nelson Pass. NEITHER were limited by folks telling them what the book says or what "THEY" can or can’t do. Brother/sisters they were and still are the Chuck Yeager’s of the Amp and Audiophile world..

Not a good idea to quote 40 year old STUFF, from a 17 year old threads..

Keep up OR enjoy your 400.00 amp... BTW I have quite a few around 400.00 class ds. Perfect for the right application..

My issue is no suggested retail price on OPs amps.

NO 20 - 40k amps or 15-20k cables either, total BS too.
