For starters I know nothing about audio and hardware, it's sad because I'm a music producer. That being said... I'm looking for something that will go from PC to device to speakers. The CR3's have one powered speaker and then the first speaker powers the second. My PC is built for gaming and the only thing I can find about its sound card is that its part of the NVIDIA GeForce 750 graphicas card. I don't know what I need for it and if it should go line out into the speakers or just auxiliary into speakers (which I feel is wrong). Either way, any advice will help me out. Thanks.
