ABSTRACT:
The method for comparing the sonic characteristics of two pair of audio interconnect cables includes the step of, in a first instance, switching, electrically connecting and transferring the analog electrical signals from an audio source to an amplifier driving a pair of speakers (sometimes speakers in a headphone set) via a pair of reference interconnect cables (sometimes referred to as a reference cable set). In a second instance, the method includes switching, electrically connecting and transferring the analog electrical signals from the audio source to the amplifier and speakers via a test interconnect cables set. The designation of cables as "reference" or "test" cables is not important. The steps of switching, electrically connecting, and transferring the analog signals to and from the reference cables and the test cables are conducted with substantially identical electrical losses and electrical signal distortion. One type of cable comparator may compare a test cable set to a short, direct connect, low loss electrical channel in the comparator. The interconnect cable comparator includes a switch assembly having signal input terminals, switchable cable output terminals, signal output terminals, and switchable cable input terminals. The cable comparator includes high quality RCA female ports or jacks directly coupled to the terminals of the switch assembly. The interconnect cable comparator reduces and eliminates, if possible, electrical losses and electrical signal distortion between electrical channels established through the signal input ports, the switch assembly, the four pair of interconnect cable ports and the signal output ports.
