Tannoy Speakers & Bi-wiring

I have a pair of Tannoy Canterbury speakers using Atma-Sphere amps. Currently I am using single wire (audience AU24) and the supplied brass jumper. Wondering what the experience of any Tannoy users out there is in bi-wiring and what kind of wires you have used. I'm thinking about trying this with a budget of about $1,000 used so really can't get into the mega expensive cables. Really curious.
