Hi Esther,
At a glance I'd be initially skeptical myself that this does anything anyone would personally notice or to justify the cost. The world of audio is particularly infected by these super cables, em dampers and all manner of improvements for a handsome price tag. Much of it is little more than marketing con-artistry that does nothing at all whilst some of what does actually have an effect, the effect is not detectable without sensitive measuring devices (

It might do something but I'd just be careful meself, see if there is any credible source validating it before buying.
Ps: I just noticed the price tag and I reckon this is likely pure grade bulls**t.
Hope is but the first step upon the road to disappointment.
