    Abstract: Systems and methods to minimize signal loss and distortions with connections of audio sources and speakers are disclosed. Fiber optic cables are used instead of conventional cables. The audio signals are kept always in the analog domain, no matter if they are in optical or electric format. The strength of the audio signals can be controlled by a volume control unit. A small amplifier unit can either directly plugged to speakers are connected to the speakers via a short speaker cable. A preamplifier is no more necessary in the system.
