The Performance Evaluation of Hi-Fi Interconnection Systems

Audio-cable is one of the most critical elements of a modern Hi-Fi system, mainly because it always introduces distortion and attenuation on the transmitted signal. Today the manufacturers produce cables with different features, suitable to transfer the various audio signals, such as low-power signals (from CD-players, musical instruments) and high-power signals (from the amplifier to the speaker). The performance evaluation of each Hi-Fi connection system requires the measurement of a wide set of parameters that can become critical when frequency increases. In this paper we propose a flexible measurement system for the performance evaluation of a wide set of different high quality cables for professional audio application, reporting also some experimental results
