I am out of town this week so I'll send pics next week. I really can't tell the difference in sound quality between the two. They both play very well. I don't think you are missing much with a 38 116 from the 690. The 690 uses a pot for bass control (left side switch). That may be the only real difference that I could tell as I can really vary the bass anyway I want.
