Phonosophie / I. Hansen Vertriebs GmbH is a prestigious German high-end audio equipment manufacturer based in Hamburg, founded and led by Ingo Hansen (born 1951). Operating from Luruper Hauptstrasse 204 in Hamburg since 1986, the company specializes in audio tuning, accessories, and innovative enhancement technologies that aim to make music sound as if you were experiencing live performance. After completing four apprenticeships (machine builder, engine mechanic, refrigeration/air conditioning technician, and businessman) and co-founding the Schauland electronics retail chain, Hansen established Phonosophie to focus on authentic sound reproduction without commercial compromises. The company stands like no other in the hi-fi industry for equipment and room tuning at the highest level, offering amplifiers, SACD/CD players, cables & connectors, and specialized hi-fi accessories. Phonosophie's unique approach involves elimination of interfering electromagnetic fields using their proprietary Aktivator technology, with Aktivator glass chips for interference suppression being among their most effective products. Their product range includes integrated amplifiers, power amplifiers, pre-amplifiers, phono amplifiers, standing speakers, active speakers, subwoofers, CD players, turntables, network players, speaker cables, power distributors, and line filters. Hansen was among the first in Germany to emphasize the importance of high-quality accessories, and Phonosophie maintains its own equipment line including a famous turntable based on Thorens, serving discerning audiophiles through specialized HiFi dealers and regular trade show appearances throughout Germany.
