I own the Signal Cable Component Video cable. That thing is huge, and thick. It actually took me a few days of light bending of the cable so I could actually maneuver it around just to hook it up between my TV and source. I love it. The thing is detailed, and did make one hell of a difference. A great value there.
I visit another message board to where a lot of members have gone the Signal Cable route. While I have no experience with their other products, I gathered that for the price- its damn difficult to beat them.
Don't expect nirvana with Signal Cable, just expect exceptional value. It seems to be the prefered cable for those doing Home Theater. It may or may not suit your tastes for critical listening.
Another plus for Signal Cable is the exceptional costumer service. Odds are you will be dealing with Frank (the owner) through any questions, issues, or transactions!
Highly recommended for inexpensive solutions !
