High E string is being overpowered...suggestions?

I love my concert, but there seems to be a few things every couple of weeks that creep up with it. This time, it's that the E string gets lost in the mix between the other strings. The uke is certainly a heck of a lot livelier than my soprano (when I hold it while people are talking at normal room volume 10 feet away, I can feel the whole instrument vibrate).

I'm thinking the Aquilas are overpowering it and I'm considering moving back to flourocarbons to balance the sound out. The issue is, when I had the M600's on before I'm almost certain that the E string was still getting lost. Is there anyone else that has had this issue on older solid ukes and found a remedy? The other three strings sound fantastic, that little guy just can't keep up volumewise.

Could be the instrument itself just doesn't resonate well at that pitch. In that case tuning to another key could help.

If you think it's more likely a string issue - well, balance is our middle name:
