Well, there's bad, then there's cell-phone bad!
I am pretty sure you don't sound as bad out in the room as it would sound if someone held up a portable recording device. Once the sound of the room masks the music as much as these demos did, I am afraid you can't really tell WHAT you are listening to...
As I said earlier, I am pretty sure I could come to one of your gigs with a cheap recording device, set it up far enough away from you that the room masks your real sound, and make even your S910 sound pretty bad... Now, that doesn't mean that the S910 really IS bad, does it?
