Logical next step from Legacy Signature SEs? Around $15K...

I posted the same topic by mistake in the HT forum, re posting here. I actually only use stereo.

Honestly, I think Legacy in general has the best bang for your buck for speakers. And these are incredible in my room...but like always, well, what's next? And I would also like the footprint to be a bit smaller.

Mostly I am afraid of losing the end to end coherence, as these speakers go from very deep to very high without really standing out. But I am also partial to silk dome tweeters, a bit warmer sound and good aesthetics. 

What would be some of the options, where I guess, I will lose out on the bottom end, but gain midrange and high end?

Room size about 16 ft by 17 ft. Metrum Onyx dac to Luxman L509X integrated. I also use a Lyric Audio Ti 140 MK2 when in the mood for tubes. Musically everything from jazz (Blue Note, Impluse, Riverside) from the 50s/60s, to classic rock, indie rock, electronic, eclectic world music....I like and listen to every thing. So that's the main thing, the speaker can't be genre constrained. I love that about Legacy. I like Devore Fidelity a lot for example, very spritely speakers, but typically their speakers lack the body. Haven't heard the wide baffled speakers though.
