Hi, I have my pc connected to an old hifi system which I use for sound. I want to upgrade this to get better sound. I 've been searching the forums and net but always go round in a circle and give up on what would be the best solution. I own 3 spare front speakers (small centre and bookshelf fronts) which I had connected to my AV receiver (home cinema) setup. I might add a subwoofer at a later date. I generally use the PC for games and a little for music. What is the best (cheapest) option available to me to connect these to my PC? Or should I forget this option and just for a Logitech 5.1 solution. Thanks.
