Who makes budget speaker cables which are truly “good” or “exceptional” in quality?

Last week, I went to pick up a subwoofer from a guy that I had bought it from via an online forum. 

He lives in a huge huge mansion in an exclusive neighborhood. He makes a living by designing hi end cable for the Pentagon. 

I thought he he would be the perfect person to pop the question: are expensive speaker cable and audio interconnects worth the money?

He said that for high frequencies in military applications that are beyond what the human ear can hear, yes. For home audio, they make no difference. Cheap Radio Shack cable is fine. 

Signal Cables - all of their stuff sounds great, and beats competitor products costing over 5x as much. I have used their interconnects, speaker cables and power cords. Most recently,  I swapped out my PS Audio AC-12 (a $1,200 power cord) for their best power cord (which cost about $250.) I also use their connector for my massive REL sub. Their speaker cable is my favorite product; it's the best value I've ever seen.

To me and my opinion, cables are very important , depending on speakers and equipment . Simple rule high end equipment require high end cable , cheap equipment you won’t hear a thing  . And depends what kind of sound do you prefer, because cable in the system are like tuning the instrument . I like acrolink or esoteric, of course you might not like that sound .

Douglas Connection makes wonderful cables that are of exceptional quality. I will try and find a link for you.

I would look into Transparent Audio  "The Wave' speaker cable. I find it very very good for the money.
