problem with the marmite analogy (as has been said) is that nobody would dispute that marmite has a taste.
the blue box is asking people to accept that a technology that is hiddent from view, and completely seperate to the hifi affects the way it sounds.
Plus the fact that Marmite has an ingredients list saying exactly what products you are putting on your toast. So, really, it is a completely useless analogy.
A better analogy would be that putting the Marmite pot on the table in front of you while you eat will change the way you think the food tastes. And it probably could, but it would be doing it vicariously in one way or another. But some people would refuse to accept that is the most likely explanation and claim the Marmite pot really is changing the food. Probably becasue that special pot of Marmite costs 700 squid :JOEL:
