Yes, all Nordost interconnects are shielded.

It is an accepted practice in the cable industry to have an impedance variation as high as 15% and still rate the cable impedance as 75 ohm or 110 ohms. However our digital cables are within 1% tolerance of the correct impedance which is either 75 ohm or 110 ohm AES/EBU. Nordost digital cables all use Micro or Dual Mono-Filament technology to remove timing errors and jitter. The result is superb performance you can hear.

Our loudspeaker cables are flat because the extruded FEP method of manufacturing that we employ allows us to precisely space conductors with a very high degree of precision. This precise geometry achieves very low capacitance and inductance – numbers that translate to much better sonic performance.

Micro Mono-Filament technology is a proprietary method of manufacturing cables to minimize the influence of the insulation on the conductors. By winding a single, FEP filament in a precise spiral around each conductor, before extruding an outer FEP “sleeve” over the top, Nordost has created a structure combining the best available dielectric material while spacing the insulation away from the core. This minimizes contact and dielectric absorption as well as creates a virtual air environment. The spiral filament also delivers excellent mechanical damping and ensures superb geometrical precision.

Unlike Micro Mono-Filament which uses one FEP thread, Dual Mono-Filament technology uses two, which are wound around each other and then around the conductor. This introduces an even larger airspace and provides less interaction between the insulation material and the conductor, thus improving performance.
