bro, still have?

Basically speaking, it is a Digital to Analogue Converter. Soundcard are DAC as well. Digital signal from your computer will be converted to analogue so that your speakers can play out those music. This DAC is just another soundcard, just better than the onboard soundcard, plus it;s external.

So yes, with this DAC, you need not buy another sound card.

I am not sure if I am correct or not, but the S730 should only have 1 cable to connect to the speaker. 3 cables are for 7.1 system. S730 is a 2.1 system, which uses Left and Right channel (which is the green RCA connector) connects to the internal amp, split it into 2.1 channel. Do note that this DAC only support 2 channel, which is left and right channel. For 5.1 or even 7.1, you will need a sound card or a dac that support multichannel output.

2.0. I haven;t seen a DAC with support for 2.1 before. Usually, what they do is they take 2 channel (left and right), run it thru a xover which will isolate the low frequency and push it to the sub. All this isolation does not happen on the DAC, as the DAC just output whatever it is feed. The isolation happens on the amp itself, same as the S730. Notice that there isn't a subwoofer connection to the amp, just left and right channel is feed to the amp

By the way, we are not talking about multichannel soundcard here, before other people start shooting at me.
