Hello All. So, I am going to be hooking up a pair of TriTrix speakers (big ones) as well as two BIC America Venturi bookshelf speakers behind me on the other side of the room. I will be powering the speakers with a stereo receiver hooked up to my computer. I am wondering: would investing in a sound card benefit me? I'd like to consider myself a junior audiophile, I can tell the difference between $100 and $400 headphones, I also listen to a lot of music, and I can't manage to listen to a song that crackles. I will be doing a fair amount of recording for vocals and vocal percussion. If I were to get a sound card, how would I hook it up, just with the standard Green 3.5mm jack or using multiple outputs? I'd have probably $40 to spend tops because I'd like to save the rest of my money for something non-computer related (I have a $100 Visa gift card). Thanks everyone!
