I want to believe in these things, because it is a relatively cheap tweak. I did notice that there were just a handful of set ups at the recent audio show in NYC that used any kind of cable lifts, I mean like 2-4 out over 100 rooms. I found that more than interesting. But you know, for a couple of hundred bucks I am going to give it a try - they do look somewhat cool, and I'm pretty sure they can do no harm. Hope I'm blown away, but won't be too disappointed if I'm not.
