They also collaborate with the SAE Institute Ljubljana as lecturers and offer practical lessons and recording hours to the students of this institute and also of the Multimedia Institute and Academy (IAM). The rather impressive list of their clients is mainly due to the knowledgeable crew of the studio, with another reason also being their innovative technical solutions and some unique, self-developed equipment pieces. In 2007, due to their reputation, they were visited by the editors of the American audio magazine Tape Op which then included a multi-page coverage of the studio and the people who work there.
