Are speaker jumpers worth doing? Opinions vary

Now i am not on the expensive range of gorgeous gear many have on here... but i am happy with the set up i have. I run Monitor Audio BX5's as my main stereo speakers & as many they are bi wire. I have tried doing bi-wire wires from the Yam Aventage amp & could not tell a difference between them and my chord carnival silverscreen. I just have the standard gold plated type links, should i buy 1m of good speaker cable & make some? is it worth it or only worth it on a much better system? Only asking as i like tweeking.
