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

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?
