Congratulations Atmasphere!


I noticed today that Ralph Karsten (whom regular and even occasional participants in this forum will of course recognize as the designer and proprietor of Atma-Sphere Music Systems, as well as a uniquely valuable contributor to the forum) was granted United States patent number 10,469,042 on November 5, 2019. It covers an audio amplification technique he had indicated here that he has been developing, which in simple terms appears to me to basically be a clever combination of an analog-to-pulse train converter (as used in traditional class D amplifiers for example, among other audio-related applications), with an output stage employing circlotron topology (analogous to the topology used in his OTL power amplifiers, but utilizing solid state devices).

Link to the Patent.

Congratulations Ralph!!

But I am curious if your new amps would be usable for my Linkwitz LX521.4 open baffle speakers?
The class D amp acts like a voltage source similar to the Parasound, so it should work. Like any class D amp it is energy efficient.
Without tubes, will it be possible to produce a low-to-mid power amplifier at a price somewhat competitive with other fairly advanced class D amps ? Below TOTL pricing ?

We think so.
