NBS Audio Cables was founded on the simple philosophy that cables should deliver the full resolution of a system.
Noise, in a cable, can and will affect the audio frequency range and interfere with an audio signal. The most common noise, Radio Frequency Interference (RFI), affects a cable directly in the audio range. RFI presents itself as hiss, commercial radio broadcasts, intercom broadcasts, or any other radio signal broadcast in the audible range. Another source of noise is Electromagnetic Interference (EMI). Whenever electricity, i.e., an audio signal, passes through a wire, it produces inductance that creates an electromagnetic field. Because EMI manifests itself at a high frequency, it is commonly believed not to interfere with the audible range of frequencies. However, all frequencies demonstrate harmonic structures. Even if the cause of EMI is outside the audible range, the upper and lower harmonics of a given frequency often present themselves within the audible range. At the very least, EMI causes degradation of audio frequencies.
The RCA connectors employed on our higher lines are the exclusive design of Walter Fields. These connectors are manufactured of gold-plated beryllium copper for greater conductance and a specially plated chromium barrel to reject RFI and EMI. The combined result puts the NBS philosophy into practice by achieving a dramatically lowered noise floor, maximal dynamic range, and the ultimate in information retrieval. The quality craftsmanship of NBS cables allows us to extend a life-time warranty to the original owner.
