All Nordost cables are hand built at their factory in Massachusetts, USA. All speaker cables are terminated with Nordost Z plugs using a proprietary formula of high grade silver solder. These light weight, tight fitting banana plugs are made with gold plated Beryllium copper. This low mass design preserves the low capacitance and inductance of the speaker cable at the termination point. All Nordost cables are made with extruded FEP and they are extremely durable. Which makes them the natural choice for Home Theater or Hi-fi systems.
