Biwire Cables: Two Seperate Runs or Single Run

Unless someone has your system, it is unlikely they could really predict an outcome. I have found a little improvement in one system using double runs of an Audioquest cable that can also be internally (single) biwired. A little better low level detail. The downside is only that the double run will cost twice as much.

Some biwire cables on the market are already double runs, such as the Analysis Plus "Bi-Oval" biwire cables.

Jon Risch has conducted some tests on the subject and you can find the results on his website at Audio DIY notes & tweaks .

In theory, separate runs of cables for the highs / lows should be superior to a single run that is "internally" bi-wired. This has to do with removing the lower current high frequency cables from within the field of the higher current low frequency cables. As to whether this is truly audible or not will depend on the resolution of one's system and / or the hearing acuity of the listener. As Sugarbrie mentions though, the "technically superior" method of using separate cables will instantly double your costs. Sean
