The Better Cables Silver Serpent XLR cable is a great sounding balanced audio interconnect. It is an outstanding Silver-Copper hybrid analog XLR interconnect that is sonically revealing without the harshness associated with most pure silver interconnects. The Better Cables Silver Serpent ensures silky-smooth audio reproduction using our advanced, dual conductor, twisted pair configuration conductors with extremely low capacitance measurements. The Better Cables Silver Serpent features 99.999% pure silver coated conductors. The hybrid construction gives all of the sonic benefits of silver (dynamic high frequencies) and all of the sonic benefits of copper (deep, tight bass response). The Better Cables Silver Serpent is an excellent choice for connecting XLR balanced sources, such as pre-amps, amplifiers, and any device with the XLR connectors. Balanced lines are the preferred method (for hum free) interconnecting of sound systems using a shielded twisted-pair. The principal behind balanced lines is that the signal is transmitted over one wire and received back on another wire. The shield does not carry any information, thus it is free to function as a true shield. This circuit's shining virtue is its great common-mode noise rejection ability. The concept here relies on induced noise showing up equally (or common) on each wire. It is mainly due to EMI (electromagnetic interference: passing through or near magnetic fields), RFI (radio frequency interference: strong broadcast signals), noisy ground references, or a combination of all three. Our Silver Serpent XLR cables exhibit exactly equal impedance from each line relative to ground, guaranteeing equal noise susceptibility. Since the balanced input stage amplifies only the difference between the lines, it rejects everything else (noise) that is common to the lines. The combination of silver, low-attenuation, and top-notch quality insulation makes this a world-class audio cable with no equal at ANY PRICE.
