Abstract
Abstract Cabling (10) is provided for interconnecting amplifier (12) having a positive side (14) and a return side (16) to a load (18) having a positive side (20) and a return side (22). The cabling comprises a first open circuited conductor (24) having a first end (26) connected to a selected one of the amplifier positive side (14) and the amplifier return side (16) and having a second end (28) extending towards and terminating free from connection to the load (18). A second open circuited conductor (30) is provided which has a first end (32) connected to a respective one of the load positive side (20) and the load return side (22), said respective one being of a different polarity than the polarity of the selected one of the amplifier positive side (14) and amplifier return side (16) to which the first open circuited conductor (24) is connected and having a second end (34) extending towards and terminating free from connection to the amplifier (12). A first amplifier-load connecting structure (38) serves for electrically connecting the amplifier positive side (14) to the load positive side (20), the first connecting structure (38) being wound about at least a majority of the length of a selected one of the first and second open circuited conductors (24,30). A second amplifier-load connecting structure (40) serves for electrically connecting the amplifier return side (16) to the load return side (22), the second connecting structure (40) being wound about at least a majority of the length of a selected other of the first and second open circuited conductors (24,30). Improved sound results from use of such cabling.
