I learned a lot from Gaudi, the home-built audio system that preceded Gaudi II. I documented and uploaded them to my previous homepage 'Tonochi's Audio Room'. I reprinted them to a supplemental document after editing some parts.
Now I see some misunderstandings, groundless beliefs and lack of experiments and measurements in this document, but lessons learned from experience are important, and they are the base of Tonochi Theory. So, I decided to reprint the article.
