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

In a nutshell, reduced distortion and less heat than MOSFETs

I guess we will have to wait for your distortion plots to determine if your amp measures less than the ncore or purifi amp, which is already far below audibility. As for less heat, that seems like a small advantage, if any, at best, which you have noted. Personally, I don't really see a compelling case for GaN at this juncture.

Class D outperforming tubes is nothing new. It happens! Has happened for a number of years. It all depends....   Class D stopped me from going to tubes over 10 years ago.    Smart of @atmasphere to open some new horizons when he felt the time was right!

I am in Baltimore/DC metro area. Looking forward to an opportunity to hear these. Have heard Atmasphere OTLs many times in the past at Capital Audiofest. Maybe next one but hopefully sooner.

Would the dead time be more like, or analogous to, crossover distortion, slew rate distortion, or neither?

Neither. At least in our design, its responsible for lower ordered harmonics. We can see that there is a cubic non-linearity, as (like our tube amps) the 3rd harmonic (treated by the ear the same as the 2nd) is the dominant distortion product.

 

 

@atmasphere...Ralph, is your design a module like most of the others?  I ask because I would assume the money would be in selling that module to others?

 

Wonder how much B&O has made off of their ICE modules?

Ralph, is your design a module like most of the others?

It is a module; because of noise concerns that's really the best way to do it.
