dark corners where capacitors lie
... all topologies use capacitors.
One just needs to understand what their disadvantages are for a given application.
With correct usage, capacitors are in fact a gem.
We need capacitors, just like we need transistors, FETs and vacuum tubes. I myself don't love tubes much as I don't love any electrical component. Like what Sir 2ny said, I just use them to the best of their abilities.
Electrical components designed and layed out properly beats the hell out of the vacuum tubes vs SS argumentation.
