Fifty years of passionate pursuit, including constant reading, major multiple year upgrade cycles every five to ten years, an increasingly successful career and ten years of season tickets to the symphony and lots of acoustic jazz concerts. During the time, an extended period to study interconnects of hundreds of hour, and similar comparisons of speaker cables and power cords. In the last twenty years it got much easier to the point I mentally decided what I wanted and finally able to pick the exact components to achieve it.
