I have both the canare and he cat 5 cables made into interconnects, they sure work very well. The canare is very neutral though. The cat5e is something i feel that never really go wrong in most cases, when done properly its packs all that you need, bass, stage, in a cheaper price tag.
I have had them as speaker cables interconnects and as hookup wires for my equipment. The only thing is that its not very flexible and can reuslt in breakage.
