bi-wire question

can you use two exact sets of wires to bi-wire instead of one set split? is there any advantage to the sets that are internally split? thanks for any help you can give. regards
External biwiring is the best by far. This keeps the highs and lows separated. In the case of internal biwires, in most cases, the highs and lows are too close to each other in the cable jacket.
Makes no difference. Even less than bi-wiring itself.

Everyones system is different, search the archives as this has been discussed many times and usually ends up in a heated debate, sort of like the power cord thing! In my system double runs are best.
