you need two DAC cards to output to your B&W 804's and your Sub. If you don't have any analog sources you don't need the ADC (analog in card).
As a preamp I found the tact to be good but not great, you have to replace the powersupply with an upgraded one from Maui Mods... go to Tacthackers on yahoo groups to ask these questions.
