Reiner Gläss has specialised his development skills in the area of sound optimisation. His aim is to be able to reproduce the full potential of data-carriers in CD format.

His patent-pending CD Sound Improver has been purchased in its 1000s by demanding high-end customers around the world. By carefully bevelling and darkening the edge of a CD it eliminates light scatter. This leads to noticeable sound improvements for CDs, better picture reproduction for DVDs and more reliable reading of data CDs.

The Disc Cleaner cleans discs thoroughly yet carefully. This optimises the sound and often allows for lost data files to be readable once again.
