Dumbo AC Crossover

The Dumbo is the first  AC crossover able to improve the audio performance of any digital source and preamplifier.

The Dumbo not only decouples the matched component from the AC power but it "re-designs" the power coming out increasing the break-up point.

The Dumbo AC is so effective that enable to turn medium class components into high class ones and to turn high class items into superior "Hi-End" products.

Extraordinarily the Bluenote is offering the Dumbo AC free of charge for any purchase of the STIBBERT BLACK PEARL during the1^st of February 2008 to 30^th of April 2008!
