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! “The definition of music improved as a whole and then into details, for instance the DVDMagic was able to make bass lines in particular less flabby with superior timbral qualities, while the treble gained in resolution and control. The overall effect of the DVDMagic was a discernable improvement without stifling or highlighting any one part of the music tested. For £20 the DVDMagic is great value and highly recommended for improving sound quality and as a tool for breaking in new hi-fi.” HiFi World September 2005
