Blue Circle Audio

History

Feb / 2004

It's a fact that things change and evolve with time. This certainly holds true in the audio industry and Blue Circle is no exception. Much of what is contained in the following still holds true but in many other ways Gilbert's design philosophy has moved beyond these two white papers. So, we relegate them to the history page.
Is there a new white paper in the works? Maybe, if we can drag himself away from designing and sit him down in front of a word processor. So far all we can get him to write is, "Simplicity, Artistry, Music."

"Engineering White Paper I" A brief description of the theory, research and engineering techniques used in the single-ended series of preamplifiers and power amplifiers.

"Engineering White Paper II" A brief description of theory, research and engineering techniques used in the Blue Circle 20 Series of preamplifiers and power amplifiers. Engineering White Paper II

With advancements in technology (and the fertile imagination of you know who) it is inevitable that some products will be revised or replaced.
