What does one purchase after owning horns?


I have owned Avantgarde Uno's and sold them because of the lack of bass to horn integration. I loved the dynamics, the midrange and highs. Now faced with a new speaker purchase, I demo speakers and they sound lifeless and contrived. The drama and beauty of live music and even the sound of percussion insturments like a piano are not at all convincing. I have an $8k budget for speakers give or take a thousand. My room is 13'X26' firing down the length. Any good ideas will be appreciated. My music prefrences are jazz/jazz vocalist.

Just an add on. I have always placed dynamic range as the most important virtue of any system. However, prat is very very close in importance to me . I need to follow the "playing" of the musicians. There is tonal coherence and agility coherence. By improperly matching damping characteristics between amp and speaker, you can ruin prat.
Ralph, Can you elaborate on exactly WHY the Avantgarde speakers are "meant for" SS amps? And is there an SS amp-type which would work similarly to a tube amp (or at least in a way such that the speaker would think that it was looking at a tube amp)?

I ask because I recently tried SS amps (zero NFB, Class A) on my horns and found myself enjoying the combination. I have not spent enough time since the earthquake here listening critically to get a handle on them yet and my ultimate goal is to bi-amp, but so far so good.

No doubt I'm in the minority here, but my primary reason for using horns (waveguides being a type of horn) is radiation pattern control.
"lack of distortion"

That's a tough case to make in reality I think.

I'll buy radiation pattern control as a another unique attribute of potential benefit.
