I have a mint condition 6ft pair of DR Acoustics Vulcan speaker cables. Spades at amp end, locking bananas at speaker end. These are silver infused copper cables filled with micro silica for vibration control. You can read more on their website. I've used them in my system for about 2 week and I couldn't tell a difference between these cables and a piar of Siltech 770L. Check my feedback and deal with confidence. Not interested in trades. Price is firm.
