The cables I ordered were NXG Pro "Sapphire Series." These were even recommended in this site for the budget system. The price was right and I also do not believe price is much of an indicator. However, no one seemed to have an opinion on these in this forum. The construction is ok. The ends are gold and have a plastic collar that unscrews. Soldering joint are ok also. The characteristic that I didn't like were that the jacket was like shiny plastic vinyl and the cables were not very flexible, even though in the description they were billed as "super flexible." The excess cable did not drape down behind the rack very well. For the money, I like the RadioShack cables better, but they don't come in legnths less than 6'.
I need 1-1/2' foot legnths and there aren't alot of choices in this legnth for component cables. I hope I have better success with the Dayton cables I ordered. I haven't seen the Velocity cables and there were not any opinions here. Velocity is mentioned as a recommendation in the $5K system on this site. There are some sites where you can find these at steeply discounted prices. If you have any knowledge of the Velocity cables, I would like to know for the future.
