No, I don't believe the story and I thought I made myself clear in the MMMicro1 thread. I mention it here only for the obvious symmetry to your experience of going from the MM3 to the Q1. It too was a big to small speaker move for similar reasons, "IF" one is willing to believe JTinn's story. I don't believe it. Does he know that you prefer the Q1 to his MM3? I wonder what he would say to that?
I also don't think JTinn found any build quality issues with the Q7 like the ones you found with the MM3.
