The presenters in our webinars

Holger Wachsmann

Holger found his way to in-akustik in 1996 after training and working as a communications electronics technician, and has made a name for himself in the hi-fi scene over the years. Initially, he was responsible for cable planning and looked after our most important global sales partners. Gradually, his area of responsibility shifted to product development, for which he is now fully responsible. The development of our AIR technology is certainly a true milestone in his creative career.

Marius Ingold

At in-akustik, Marius takes care of the raw material of good sound: electricity. After training as an "electronics technician for industrial engineering" at Siemens, he completed a Bachelor's degree in "Electronics and Computer Engineering". As part of his Master's degree in Embedded Systems, he worked as a student trainee at in-akustik, and discovered his passion for music in the process. He has been working full-time in in-akustik product development for 3 years now, dealing with “electrifying” topics.

Guido Lay

Guido definitely has high-end in his blood. At in-akustik, he has been responsible for marketing our high-end sales brands for over thirty years now. Guido can’t really imagine a life without music (or bikes). He has acquired his extensive know-how through many years of self-education, and has always kept up with the times. Nostalgia meets digital: His expertise ranges from conventional vinyl playback to high res audio streaming. And he also manages our IT ;-)
