I have to be the first to admit that I don't know anything about speaker wire. I always thought wire is wire is wire until I bought my new surrond sound system. I had just bought a new 50" TV and I bought the surround sound system to go with it. My daughters boyfriend offered to come hook everything up for me, since he had worked in home theater during college. Of course I had no problem with that.
Well he showed up and the first thing he said we need to go to Best Buy! I said what for, he said we need to get monster cables for your speakers. I told him it comes with speaker wire and he just shook his head and said trust me Mom. We went to Best Buy and he picked out the monster cables he needed and said this is on me!
When we got back he said I am going to show why we went and bought these cables. He first hooked up the speaker wire that came with the speakers, put in a movie and I said wow nice sound! He just laughed at me and then said wait. He then hooked up the monster cables and yes even I could hear the difference. I was totally amazed that a wire could make a difference in the sound quality. I was sold!
Lesson of the story - if you are going to spend your hard earned money on a good sound system and tv make sure you spend some money on good speaker wires to get the best sound out of your system!
