Sonus Faber Liuto Tower or Sonus Faber Cremona M, new or used. I've heard the Cremona M in an extensive audition, and I *know* these would give you what you're looking for in spades.
These two have an excellent, transparent midrange that serves both acoustic pop/folk and electric blues well, from expressive voices to acoustic guitars to wailing guitars. The bass is lively and punchy. They also look fantastic.
If you have the space, you could go with Magnepan 3.7, possibly supplemented with a sub or two to bring out the kick drum and electric bass for the blues.
