All of them are good cables.
I may be wrong but Signal is using canare and belden, like blue jeans. The difference is in the terminations.
I shopped with blue jeans - I have canare 4s11 for speaker cables @ about $30 for a 10ft pair, and I do not know why I should pay more. For Interconnects, I have a short bl-1 and 4ft long canare lv-61. I prefer canare lv-61 over bl-1 personally.
You can't go wrong with canare, especially with their rca plugs.
In my opinion, they are the best cables period. Those who disagree with my opinion will at least agree that they are the best for the money, I am sure.
