Low Bandwidth or Better Sound?

Quick question, do you prefer lower bandwidth or higher quality sound? We're hoping to make more music available (commercial free even!) if it pans out, there's a choice between "cd quality" but 128k or the current lower bandwidth 56k. Personally, I kind of like the 56k sound and can't tell much difference. Now is your chance to speak up! less filling or crisp(er) sound?
