Sorry guys, but I have to agree with Bob, I think the quantum aspect of these thing is pure marketing BS.
Not that I'm saying that they don't or can't work (and for less than ten bucks I know that one of these days I will be trying them one of these days) Stranger things have ended up making a positive difference in my system. But I think the explanation is a little hokey. Which is a shame because instead of focusing on the possible sonic benefits of a device like this, BS marketing tends to drive the discussions into the realm of whether it can work in the manner it is being advertized as opposed whether the actually does help and in what way.
I have said this a number of times before, but as an engineer, at work I need to understand how and why something works so we can monetize the technology, but as a consumer, if it helps my system sound better, I really don't give a rats @ss why, I just want to enjoy the results.
