Warm Audio offers two cable lines—Premier and Professional—to provide as many options as possible in two different price ranges. Both lines leverage the cutting-edge construction of Gotham AG, based in Switzerland, and offer exceptional audio performance, near-perfect signal transfer, and optimal reliability (which is why they both come with a lifetime warranty). Both cable ranges produce fabulous results, but the Premier range adds superior features such as gold-plated connectors, four-conductor Starquad construction for powerful EMI rejection, and Double-Reussen shielding for increased RFI rejection. There is simply no more reliable, higher-quality cable on the planet, and Warm Cables are not sold at exorbitant prices—they are cables that everyone can afford!
