I have been trying cables for about six months. Nordost, audio magic, discovery, goertz, jps, silver audio, siltch, synergistic research, tara, cardas, analysis plus, harmonic technology, and nirvana. The nirvana sounds the best so far. At first I didn't like it but that turned out to be problems elsewhere in my system. As an example, my tube amp can run in pentode, 2/3 pentode 1/3 triode, 1/3 pentode 2/3 triode, or all triode. Anything but all triode sounded terrible. I read Robert Harley's review in TAS of the Avalon speakers and he mentioned that the NBS cables allow you to hear diffenent notes simultaneously and I thought it would be nice to hear that. The nirvanas were the first to let me hear that.
