New speaker suggestion

Magnepan 3.7i's then if you want to spend a little more, Sound Labs 545's
Dipole speakers limit room interaction and these two speakers punch way above their price point. They will open up a whole new world of imaging and articulation missing in dynamic speakers costing many times more. 
Both benefit greatly with subwoofers which you already have. If you use a two way subwoofer crossover the Sound Labs will hit volume levels unheard of from an ESL. The Maggie will play loud but not concert loud.
If you want to blow your doors off these are not your speakers.

@sounds_real_audio , I sort of think detail and high resolution are the same thing.
@hshifi, You do not want to go below the 3.7i is a more useful suggestion. Yes, the 20.7s are better but not 2 x better. The 3.7i represents the best value.
