Full-range recommendations

Hi all,

Looking for recs for a good full-range speaker, used, in the $3-4K range, maybe a bit more if it's worth it. I want these to be speakers I keep for 20 years or so.

My listening room for the next few years is quite small: 11x14x7; however, we'll move in a bout five years and I anticipate having a bigger listening room.

I'm running a 150w/ch LSA Statement integrated and listen to a variety of jazz, folk-rock, rock, and piano through a Rotel 1072 cd and a Pro-Ject 5.1SE tt.

I like a warm, open sound. My current monitors are Reference 3A de Capo i's. Beautiful monitors, but lacking in the bass extension - and I'm loathe to use a sub. What i don't want is a dry, neutral sound.

Let me know what other questions I would need to answer, and thank you for your advice.
