Dear Fellow Sound People, I am looking into buying a USB Sound Device in order to bypass my crap sound device that is internal in my laptop. I will be inputting it into an Allen and Heath GL2800 via RCA. Is it better to buy a USB sound device that has RCA right on it, or would it be okay to get one with only a 3.5mm jack that I would have to convert again with a 3.5mm to RCA cable. Any Suggestions? I don't want to spend too much money on this.
