Review just out on the Shunyata Sigma series of cables from Audio Beat which people might be interested in...

After recently upgrading my power cables to Shunyata and noticing a significant improvement, the past 2 days I've been testing some of their Sigma interconnects and all I can say is Wow!! Even my wife said to me she had never heard my system sound the way it did - the authority yet smoothness of the music was something I have never experienced before.
Now I'm in real trouble as I'm sure their speaker cables are also fantastic!
