One consideration regarding Audioquest biwire is that their single biwire cables are configured somewhat differently than if you were to use shotgun double runs of the same type. What they do with their spread-spectrum s.b.w. (in order to make it more economical to use) is reduce/reconfigure some of the high side conductors over to the low side conductors, compared to a double run. This enhances performance where you need it, without degrading performance where you don't need those extra conductors.
Bi-wire using single or two cables?
I have an Onix A60 Integrated that I'm running into PSB Century 600i's. Am hoping to bi-wire, but was wondering whether it's better to use two less expensive cables to biwire, or one more expensive cable with biwiring ends built in. Specifically, I'm debating between two pairs of Audioquest Type 2+'s, or one pair of Type 6 biwire cable. Any comments as to good cables I can look into at that price range would be greatly appreciated as well. Thanks!
