I've been reading about these for a while now. There are reports all over the place. Many find these "things" to change the sound of their systems. Some changes for the better and some for worse and that the effects can change by placement and number used. They are most commonly described as "stickers".
As far as "Quantum", that's just a name as far as I'm concerned not necessarily a claim. They could have called them "Audio Stickers" or "Ajax Labels" or "Fun Stickies", wouldn't really matter. Figure, about half of all stuff in audio is named after something either Hindu or Buddhist. "Quantum" is just so "in" right now like "Titanium". Lots of "Titanium" stuff right now that contain absolutely no titanium for instance. So that part is insignificant to me.
But they seem to be doing something and no one can figure out why, that's what seems weird to me. Weird enough that I might have to give them a try. Maybe they should have named them the "Little Enigma Thingies".
