..i just recently biwired my piega c-40 speakers and before doing so ..read the aforementioned richard vandersteen article and tried two different cables..in my case a crystal cable 'ultra' ..that i already had with an argento 'reference' cable and the sound was not good..then when i then used 2 seperate runs of the argento 'reference' cables the sound was superb...there probably is something to using the same cables for biwiring ...in my case it certainly was the better combination...
