Class D Technology

One of my friends is getting a pair of 48V Desktop Cherrys likely next week.  Unless we are in total lockdown, the plan is to try it out at his place, mine and one of our friends in our social bubble. Our friend is running Maggie 20.7s so should be interesting to see how it does. I have wanted to try them out for some time, but wasn't looking for anything new in amplification.

Both the switching distortion and non-linear should be addressed. True, the output devices are switching, however, the output devices are unlike other amplifiers as they are not operated in the linear region, which is not actually linear, but operated in saturation. That is a good thing. There is a lot less variability in the saturation region, which leads to less distortion, not more, from an architecture potential standpoint.

While technically distortion, the filter is not removing distortion in the the sense of a standard linear amplifier which would be distortion in the audible band, but harmonic products above the audible band.

Obviously No Switching distortion.

I also understand the weaknesses somewhat. 1. Non-linear & lots of distortion that needs to be cleaned up with an output filter.
