These so-called "brown discus" are no threat to BlackDiscus - in tests, the black version trounced the brown one when attached to speaker outputs, headphone jacks and power cords. In addition, the brown version has handling problems, leaving unsightly smears on equipment.
The durability of the brown version is also dubious - the chocolate-colored outer layer appears to be made from, well, chocolate. And not decent audiophile grade high-altitude single-farm stuff either - just simple commercial grade milk chocolate. And there's worse to come - analysis of the inside showed that it contains Arachis hypogaea, a potent allergen, as well as butter, which is implicated in all sorts of things. They even admit this, apparently, when they dub these devices "Reeces Peanut Butter Cups" - not exactly a catchy name!
Furthermore, in blind taste tests, 10 out of 10 dentists preferred BlackDiscus, handily besting the chocolate covered device.
- don't use these brown discs on your audio system
- don't use brown discs if you are allergic to "pea" nuts.
- use BlackDiscus on your audio system - much better results all around
- do not eat BlackDiscus (unless you want to pursue a closer financial relationship with a dentist)
