I have owned some high end cables by various manufacturers- Cardas, Nordost, Discovery, AudioQuest and others. I needed a 1 meter balanced cable for an Oppo BDP-95 I had recently purchased. I was using a 2 meter Discovery Plus 4 cable, which probably was close to $500 new, but didn't want the excess cable wound up and velcroed to a support on my audio rack. After researching a little I thought the cables looked very promising and comparitively they are inexpensive compared to what I have become used to paying.
I've only used them now for a couple of days, and am very satisfied. No RF hum, a clear and bright signal, I feel I am getting the full benefit of performance in my system using these cables. I will probably buy more in the future and would highly recommend them to anyone looking for a well constructed great sounding cable- and save some money vs. the "designer" brands I mentioned above.
