I've actually heard some very good things about the Anti-Cables. Speaker cables are very system dependent.
I think the best easy-tweek change one can do is at the source, and I will assume that most are using CDs, so I wonder how many folks are darkening the edges of their CDs. This tweek alone is like a big upgrade in power cables and it only costs the price of a "Black Sharpie"
We have a very small Audio Group here in Salt Lake that met at a "Home Dealer" to hear the new Focals, well, I ended up asking them if they did this to their CDs, I could tell the answer was "no" by the look on their faces. So the dealer went and got a Sharpie marker and blackened the edges of a Rickie Lee CD and popped it into the player; on the very first notes, their jaws literally dropped.
I find that I cannot listen to a CD without this treatment.
Just blacken the very outside edge and the inside area around the spindle. Here's a couple of pics to make it clear.


Now look, I definitely don't want to hijack this thread so if people want to reply, maybe we should start a new thread.
