It usually makes a significant improvement to replace the stock links provided with the majority of speakers with a better link. Many companies make replacement links ie Nordost in varying levels (cost). Another option if possible is to make a short set with the same cable that you are using as your speaker cable. There have also been some testing as to weather bi-wire is better than a single run + a link or jumper to the other set of speaker terminals. I have always run my system bi-wired and have recently switched to a single run with a jumper made from the same wire (Nordost Valhalla) and have noticed an improved sound. I believe much of this assessment or study has been done by Nordost. Main message is to replace the stock jumpers-you will appreciate the benefit (if you have a good store close maybe they will lend you a sample or two)
