I have a long rca on my home theater setup to the sub it is the dhlabs subsonic. That made the sub both tuneful and go way deeper I had gold furutech ends put on it I was shocked how good it was for how little I paid. I also have a 6 foot pair of redwave powercord with the top of the line furutech rhodium plugs on them. They are really good I like the furutech powercord that is about the same money on many things just a bit better but not on everything better. I also have dhlabs speaker wire a short pair on a set of monoblocks in my bedroom they are real competitive with transparent ultras. They seem to make some good wire a value pricing

Just received a pair of Air Matrix Cryo RCA interconnects. Exceptional quality for the money. Much better than the Nordost Blue Heaven they replaced . Good stuff !!! Customer service is off the chart too.
