I am a newbie in the digital recording world. I would like to know what econically priced sound card would be the best choice. Do I need the I/O ports of the SB Live if I am burning CD's directly from my computer or could I get away with the SB Live value? I have a ART pre-amp that I am going to use to connect my SM58 to the sound card. Does the SB Live (not value)provide a better input (less hiss/distortion) than the standard 1/8" jack of the SB Value? Is the DMANN better than the SB Live? I am only going to need one track to record simultaneously.
