Burkhard Vogel achieved the degree Diplom-Ingenieur (Telecommunications) from Darmstadt University of Technology, Germany, in 1973. He then decided to follow a general management career path in the high-tech and IT industry in Germany, Switzerland, and Austria. His passion for music and music systems made Mr. Vogel an expert in Phono-Amps and Vinyl Technology. In addition to "Slopes and Levels," he wrote the RIAA-phono-amp designer guides "The Sound of Silence" and "Balanced Phono-Amps," rounded up by the triode reference "How to Gain Gain".
