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
