I'm also using the de Capo's with a Prima Luna Prologue Two integrated amp and couldn't be happier. I listen to jazz, classical and traditional acoustic music. I never tire of listening to them. They are amazing imagers once you get the placement right and as detailed and clear as you could want. Yes, the bottom is not a slam as is the case with floorstanders, but even listening to organ music and the occasional rock and roll record I don't find that I am missing anything. They are very efficient speakers, so work well with tube amps. You definitely would not want to pair them with a subwoofer.
