I don't know about "end game", but I am really happy with my current setup.
Emerald Physics 2.8's with external crossovers (2x15" Carbon woofer, 12" carbon mid, and a 1" poly tweeter) and a Rythmik G22 subwoofer.
Lush, lovely, and articulate.
I do know that no matter what comes in the future, it will be an open baffle speaker.
