I went down the rabbit hole. I didn't read @Moke 's last post where he said his I/O is set at 7.5%-ish until just now. That's exactly where I ended up and I can't hear a difference in the tone or the volume. It just made the clip warning go away. So I guess I've got an unclipped signal working now, which is good. But I seriously can't hear the difference. And that's good too.
