acoustical-systems started as a two-person side-business in 1998. During the early 2000 we supplied thousands of selected vintage NOS audio tubes to tube amplification enthusiasts worldwide. Since 2004 we have designed all-out assault full sound systems and dedicated individualized solutions for many serious audiophiles. These unique set-ups were custom made for true connaisseurs of the audio art - dedicated and seasoned audiophiles who finally wanted perfect tailored solutions for their individual specific demands.
