I thought bi-wiring didn't matter but I was wrong. For some reason after I bi-wired my setup I heard more detail and separation in my music. I even did a blind test. I went up to my friend B&W speakers who forgot to remove those clips behind his post. I did not mention anything to him and just started to take it off. After I had it off he was like saying what the hell I did. His speakers sound definitely much better and clearer. He has been using those set of speakers for 6 years bi-wired but no one told him he was supposed to take out the clips which attached his low and highs.
Most HIFI stores would lend you a good set of bi-wireable speaker cables. Use your ears as a judge.
Speaker wires also does make a difference (unlike what most people here believe). Sure is you got regular zip vs Moster cables...you won't know the difference......try it against Kimbers or QED...you'll notice something (and its not just a lighter pocket).
