I would try signal cable speaker cables which I have very nice if your system is on the bright side they tamed my compression drivers in a very nice way.I have the Evo 3 on my table it is on the bright side for me, not sure how the vandys sound but a wicked nice speaker!I like synergistic research interconnects which I also have very neutral cable, again it's all about synergy within your system.I have tube amp tube pre which may factor into how the cables fit into my system.I am sure you can find good cables without spending s truck load of cash.
