I was very bored a few days ago and decided to play around with my speaker cables. I always thought speaker cables all sound the same as long as they are of sufficient size and contain high purity copper. Boy was I wrong. My previous set-up had a pair of Pro-Link 12ga for the LF and Accostic Research 16ga for the HF. All I did that night was switch them around. What I heard was almost a day/night difference. First I thought I was hearing things, then I went back to the original wiring and back to the new wiring and heard a difference every time. My LSi now really sings and everything just improved big time.
I know some of you are thinking I'm nuts but I wasn't the only one who heard a difference. My mother used the system the very next day and asked me if I changed anything. She said the bass was much better and vocals sounded more realistic. Now I know I wasn't hearing things. My mom uses my system about 2-3 times a week while I'm at school.
One thing I know for sure now is that the LSi are very sensitive to the components they're hooked up to(yes, even speaker cables).
