USB power. Modi 1 needed Wyrd to avoid sounding thin, weak, grainy, and unfocused. With Wyrd, Modi 1 improves significantly. I didn't bother with the Wyrd factor in the graph. Too many variables. For example, supposedly the Hugo shifts to the left and jumps upward 13 spaces with the Wyrd. I'm surprised Chord hasn't hired Jason and Moffat yet to do their USB properly.
