Audio cables are required to carry very low level signals, which are typically in the range of -70db to -120db. This makes them very susceptible to electromagnetic interference and to capacitance changes caused by vibration, flexing and even temperature changes. Simply handling a cable can cause noise. The solution to these problems lie in the design and quality of the cable, and Piranha cables have been carefully designed and manufactured without comprimise, for maximum performance and reliability - guaranteed by the brand you can trust.
