See one of my pixs on my system.. I tried various nordost, synergisticm (the new stuff), cardas, transparent XL, harmonic tech ( my fav for relatively reasonable cable, Acoustic Zen. I use tara 0.8, and the one power cords. There is a harmonic richness and rightness I did not get with the others... I can say definitively that Nordost Valhallas are not a good match, the bleach the sound. I found the harmonics to be harsh, and the various synergistics to have audible uneven frequency response. The differences were, surprising big on speaker cables, not so much on dac to preamp, and moreso on preamp to amp. Never tried the Wireworld, but it sounded pretty good at CES.
