I have not tried Audioquest in years. Though I do use their HDMI and Ethernet cables in my network with great results. I have tried Nordost Heimdall 2 and Kubala Sosna, I forget the name but it was the black one. My Ancient ARC Litz cable was better than either of those. Really the Sane Line was the first cable I found that was significantly better.
I have only tried the Shunyata Black Mamba HC and Alpha HC. I don't have a Shunyata Dealer near me. I have heard that their new Delta cable is excellent, as good as my Alpha. Go with the HC (high current)
version
of whatever cable you choose. The ARC Ref 5se and Ref 2se use 20 amp power cords. While my Ref CD7 has the normal 15 amp power cord.
