All the SPM Reference cables use silver-plated, 99.999999% Oxygen-Free Copper with a Teflon dielectric, but so what! So do a lot of other cables that cost considerably less. The key is the slow Class 1 extrusion process. Nordost specifies that each conductor is encapsulated in exactly 5mm of Teflon, with the plating and spacing of each conductor held to the tightest of tolerances. Apparently these specifications result in a fair amount of rejects, meaning cost of production is quite high. The result, though, is a cable with extremely low capacitance, low inductance, and low signal loss. Nordost also claims the elimination of reflections and the reduction of standing waves in the SPM Reference.

SPM Reference Speaker Cable

There is no difference between SPM Interconnect and speaker cable and interconnect except:

There are 32 conductors in the speaker cable, 16 in the interconnect

Impedance is 90 ohms in the speaker cable instead of the interconnect’s 110 ohms

Termination is copper beryllium banana plugs or oxygen free copper spades

Speaker cable is about twice as wide as the interconnect
