I'll be buying an SM57 to improve the audio qaulity of my recordings soon, however i'd like some suggestions on which interface to use with it? of course USB output is perferred. i don't need anything fancy, but good qaulity sound is a must. budget is almost endless (not gonna spend $1000 on recording my sorry ass tho).
