For audio purposes, like between a PS Audio Perfect Wave DAC and Transport, HDMI cables have very limited impact on sound, far less than is the case with power cords, interconnects, and S/PDIF digital cables. For A/V purposes, you are asking in the wrong forum. Personally, I have noticed zero visual difference when using different HDMI cables to my TV. Go with Blue Jeans, Monoprice, or Supra (if you want to splurge.)
