I'm looking at setting up a home system and I need some direction. I have a PodXT and midi keyoard and I have about 600 bucks to do this. I have looked at krk and m-audio monitors rokit5's aand BK5's also do I need a mixer or just a good sound card. I have Acid Pro 4 and Sound Forge 6 software. I want to be able to use the monitos for every day playback and record as well. Any help would be great.
