Warm Audio partnered with Switzerland-based Gotham AG-Europe’s top producer of boutique cables, to provide cable stock for our entire line. Our Premier TRS cables offer over-the-top features like gold-plated connectors, StarQuad construction, Double-Reussen shielding and a braided outer wrap. StarQuad construction achieves greater protection from induced noise than traditional TRS cables by using five cores instead of three, and Double-Reussen shielding uses two separate copper shields wrapped in a contrary direction to create the strongest resistance to EMI available. Premier cables also come with a lifetime warranty, bringing you serious gear that's seriously affordable.
