well, the advantage of mastering your own music is getting it to sound the way you want it to sound. i don't buy that whole "unbiased perspective thing" so long as you're a competent producer. the advantage of someone else mastering it is getting it to sound the way someone else wants to sound. sometimes that different perspective is what you *really* wanted all along, but you couldn't possibly have conceived of the other guy's vision for the tune, so you didn't *know* that was the sound you wanted. other times, the other person's master of your work will sound completely wrong to you.
