Densen DVDMagic is the only hi-fi accessory of its kind capable of improving your system. The DVD demagnetizes the sound system, and the difference is obvious to anybody, even those who are not Hi-Fi enthusiasts.
Basically, the DVDMagic is a DeMagic in 5.1 digital surround. You place the DVDMagic in your DVD player, set the volume to its normal level and press “play”. In approximately 3 minutes your Home Cinema System will sound much clearer, dynamic, detailed and transparent than before. DVDMagic cleans the entire signal path for the magnetism which builds up during playback. The magnetism results in Magnetically Induced Distortion (MID), which degrades the audio signal.
The DVDMagic sends a series of complex algorithm signals which remove the MID through your system. It may be the single most important purchase of Hi-Fi accessories you will ever make!
