Hello. I am new to the audio side of pc's, and I am planning on buying a few new things. I am going to be picking up the rs220's soon, and I would like to know what sort of sound card/ amp/ dac combo I would need to get the most out of them. Would I even need all three, or would a sound card as well as an amp be redundant? I might sound a little noobish, but again, I am new in the audio scene.
