I am breaking in new Nautilus 805's and am using the Harmonic Technology Pro-9 Biwire with superb results. These are easily auditioned in home thanks to their 30 day return policy. They really do require a long break in period (90-200 hrs.) and I think the few negative reviews are due to trying cables not broken in yet, even with cables that the dealers say are broken in I have found that they need a day or so to settle in.
