I am looking to use my PC as the basis for my home audio and theatre. I am planning on getting the TerraTec Aureon sound card which has 8 (7.1) channel sound, with a digital input and output, as I hear thats the best on the market. My PC already has a DVD+RW drive, so I dont need that. Could someone tell me what else I need for a high quality audio and theatre experience? Do I just need an Amp with speakers or do I need a pre-amp or receiver. If its just the amp + speakers, does anyone have a suggestion for an amp+speaker system that can take digital input and directly convert it to 8 channel digital sound rather than going through DAC (or does it not make a difference to sound quality)? Im looking to spend less than £500. Any thoughts / help would be much appreciated.
