I am using a belden 5t00p between my marantz int 8400 and totem hawks and it works well. It is a pure stranded copper 10awg, twisted to lower inductance and rf, sold in many places including bluejean. It provides more extension, dynamics and transparency with the hawks compared to canare 4s11 and 4s8, and kimber 4pr. It's more likely that the size makes a difference with the demanding scanspeak driver. On bright bookshelves, i prefer canare. On warm bookshelves, i prefer kimber.
