Apparently I dream of overkill! But then the reality of house and wife I mean house :-) renovations rained on my parade!
Also just read this article this morning about switching in class D amps - does anyone know what switching the ADA's use? I'm interested in learning more about this.

Cheers all.


Hi Dan,

The article that you linked is pretty good, but note that Skip uses the word "historically" in the section talking about Class D distortion and feedback. We now have output devices available with extremely low gate resistance and low energy storage, so the days of super-high-feedback being required for Class D have passed. For your reference, all of the ADA amplifiers use a self-oscillating topology and are pure PWM...there is no PCM conversion going on.

Thanks,

Andrew
