For all those audiophiles interested in clean power for your circuits, I call your attention to Jack Walton’s recent article in Linear Audio, Volume 4. The title is “A Comparative Overview of Power Supply Regulator Designs with Listening Tests”. The five published volumes of Linear Audio are available for purchase at www.linearaudio.net.
I made some follow on comments to this article, which also appear on the Linearaudio.net website as a Letter-to-the-Editor, along with Jack’s response. Good stuff!
