I wonder how well this new product will work with 16 ohm speakers? Sure, it will work, but, how effectively. This is a surprise for folks who have cherished the OTL designs for use with 16 ohm speakers.
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

@ricevs you hit the nail on the head. The only similarity will be that they are D Class.

The website lists power specs into 16 ohm. Ralph has clearly articulated all amps make less distortion into higher impedance loads so I would anticipate that is a driver still for his design. Will be interesting for someone to measure how these operate into different loads. Yes the M word….. I would expect these to work better with more speakers which would open up some new sales paths for Atmasphere. Has potential to make me a customer which would not have been likely with OTL tube amps given my speaker preferences. |
So he is adding distortion to please a certain group of people? And those who don’t prefer his particular distortion preference, not so much. Sad when marketing takes the place of producing an amplifier that does what an amplifier is by definition: something that outputs a larger version of the input, nothing more, nothing less.

My speakers at home are 16 Ohms as well as our speakers at the shop. Any amp driving 16 Ohms will have lower distortion.
@kuribo In most class D designs, the distortion sources in the design are caused by dead time and non-linearities in the encoding scheme. In our design these result in lower ordered harmonics- its not been tailored.
