At the Consumer Electronics Show a couple years ago, I ran into a good friend employed in the power-conditioner business. In the course of conversation, I inquired how his business was doing. With a protracted sigh, he stated something to the effect of “everybody is making power conditioners these days,” a fact supported by the plethora of power-conditioning/-filtering/-regenerating devices currently available on the audio market. Without thinking too hard, I came up with the names of a dozen such devices in a matter of a few seconds.
