it seems like devine intervention has made the choice between the speakers for me!!! This morning we got a surge through the electricity board which knocked out the power to everything. 2 minutes later when it all came back on, my ethernet card was broken and nothing seemed to be working. I rebooted my PC and miraculously everything (including the router two doors down) sprung into life and started working again....APART FROM ONE OF THE SPEAKER SYSTEMS. One speaker system works fine, the other one's subwoofer has stopped working....hence God has clearly decided in favour of the digital system!
