B3 Series Professional "Standard Purpose" cable Great for application where the performance must match the capabilities of the quality recorded on music CD and portable music players. B5 Series Professional "High End" cable Designed to keep presence and depth intact to capture the intended AV experience. Matched to comply with av system equipment that handles a wide spectrum of frequencies, such as uncompressed audio and digital files. B7 Series Professional "Audiophile" cable. Complies with system equipment designed to reproduce the original AV performance such as full analog and high definition, plus minimizes performance degredation over time. | Series: | B3 Series | B5 Series | B7 Series | | Gauge: | 26 | 22 | 20 | | Conductor: | bare copper | bare copper | 99.99% oxygen free copper | | Insulation: | Foamed polyethylene | Foamed polyethylene | Foamed polyethylene | | Shield (1): | Aluminum foil 25% overlap | Aluminum foil 25% overlap | Conductive PVC | | Shield (2): | Bare Copper Braiding, 85% coverage | Bare Copper Braiding, 90% coverage | Tinned Copper Braiding, 95% coverage | | Jacket: | PVC | PVC | PVC | | Sleeve: | -- | Nylon | Nylon | | | | Plating: | Gold over Brass | Gold over Brass | Silver over Brass | | Body: | Molded Plastic | Die Cast metal (silver) | Die Cast Zinc (silver) | | Connector Length: | 32 mm (1.25 in.) | 28 mm (1.1 in.) | 28 mm (1.1 in.) | | Connector Diameter: | 13.8 mm (.54 in.) | 14.5 mm (.57 in.) | 18.85 mm (.54 in.) |
Wire Gauge - A larger surface area improves signal transfer by reducing resistance.
Conductor - Oxygen free cables minimizes oxidation on the surface. Most signal transfer occur on the surface so we want to keep resistance low over its lifetime.
Shield - Additional copper braiding provides extra shielding insurance to minimize any signal disruption entering the cable.
Sleeve - An added nylon sleeve improves cable aesthetics.
Plating - Silver has less resistance than gold which allows signal transfer to be more smooth which reduces signal degredation.
Body - More expensive materials used to improve the image of the connector head (die cast metal connector head on B5 compared to molded plastic on B3).
