I'm pretty confident that your issue is the deCapo. It's a terrific speaker (I owned them for several years) that is very easy to drive, tonally neutral and wider bandwidth than cabinet size would suggest. But, but, but...big dynamic swings are the achilles heel. I feel exactly the same way about very expensive Quad ESLs, so you can hardly bitch about the deCapos given their other strengths and price tag.
I'd try to borrow a very dynamic speaker (maybe a horn loaded system) from a local dealer for an in-home audition. That should help determine what you're after.
Good Luck
