I have a Toshiba QOSMIO X500 laptop and it is quite old now. Now I want to know that does there is a need of some type of special cable which can give a good quality sound on the new speaker system. I had gone through the specification which says that the outpt is spdif ready. What this means. I have a same indication on the amplifier. I hope this will work but does any additional component needed for this.
