CLASS D MONO AMPS buy ATMASPHERE MUSIC SYSTEMS

CLASS D AMPLIFIER TECHNOLOGY HAS FINALLY ARRIVED TO OUTPERFORM ALL OTHER TOPOLOGIES 

The Amplifier is the New Class D Mono Amps using GaN Fets in a unique Patented
Circlotronic output stage…Design by Ralph Karsten of ATMASPHERE MUSIC SYSTEMS 

Rated at 100 watts 8 ohms and 200 watts 4 ohms with low distortion across the full audio bandwidth with excellent noise characteristics 

I have been using ATMASPHERE MUSIC SYSTEMS MA-1 3.0 with all factory upgrades along with NOS 6NS7 Input Tubes for many years 

The New ATMASPHERE MUSIC SYSTEMS CLASS D has outperformed my MA-1 3.0 in all areas…the resolution and transparency are simply an Amazing Accomplishment

Also I sold my MP-3 mk 3.0 and purchased the New MP-3 mk3.3

In my Audio opinion I believe the ATMASPHERE MUSIC SYSTEMS CLASS D MONO AMPS used with the MP-3 mk3.3 will offer one of the most transparent sounding electronics combinations to date…only using the MP-1 mk3.3 will offer more performance 

I have used other High End Amplifiers in my system and the ATMASPHERE MUSIC SYSTEMS CLASS D MONO AMPS outperformed all of them as well

Finally something reasonably priced from Atma-Sphere... 😂

$5400/pr SRP = $598/pr USD   Something I can finally afford... Yippee!!

I am sure double the wattage will mean triple the price tag... in future products...😊 since it just made his tube amps obsolete... Looking forward to those discounted products!!

Congrats Ralph !!   I am sure it will put everything else to shame... again.

Yes, I long for a $3000 a pair amp that sounds as good. If Ralph’s amps were made by Kinki Studio they would be around $2500 the pair. Check out:

https://www.kinki-studio.com/ex-b7

The Kinki Studio amps are $3500 a pair and sound really good, twice as heavy, twice as powerful, way more parts and great build. Srajen, at 6 moons, uses these as his reference.....2 meg bandwidth.

Maybe when Ralph retires he can make a deal with Kinki or someone and have them cranked out in China....then more of us could enjoy this quality of sound. $5400 is nothing for some but for most audiophiles....still a lot of money. I’ve never bought anything that expensive.

In the meantime you have modded Purifi based amps, and stock or modded GaN amps from Orchard, LSA and Peachtree that are really great.....all way cheaper.

If these amps are better than much more expensive amps....then this is really good. However, a more powerful version has to be in the wings.....100 watts is just not enough for some speaker systems. I would go at least 300/600/1000 watts......of course, even more money ($10K?)......but, again, if they beat the big boys than great.

@ Ric

Please go away...your next post will let us all know that you have already modded an unreleased amp from Ralph. Everything is better...peace on Mars

The GaN stuff is pretty good. I have a Class D Audio for a secondary system and it comes pretty close my Purifi’s (Mivera). Built many DIY Hypex over the years (UcD, nCore).

 

BTW - Congrats Ralph. May need to try one (or two)....

I have been watching for this, half hoping that Ralph would conclude his class D effort couldn't play in the same league with hist tube OTLs, and half hoping that he was able to pull this off, thus giving us Atma-Sphere fans a wider selection of compatible speakers. 

I don't know how many times I've sworn I would never move on from my M-60's.   Now, maybe, I should be thinking about this.

Congratulations Ralph.

Every single person (including me) is necessary in this universe. No one needs to go away. If you do not like what I say.......remember.....when you point a finger at someone.....3 are pointing back at you.....it is all projection. What I try to project is love and respect towards everyone.....because I know that everyone is divine....worthy and deserving.

I doubt anyone would send me a $5400 amp to mod.....but I am open to it. Everything can be improved.

By the way, the Mytek Gan amps are still delayed....they have a 200 watt a channel $6K amp that may come out soon......so more things to try. It never ends.

I hope Ralph can crank out these babies soon so a lot of people can get great sound for not a fortune. Blessings to all.  Peace on Earth and especially in your heart.  Love is what we all came here for.  You create it anytime you like....you are in control.
