Have you found your "End-Game" speakers yet? I have. And it feels so good!!!

I’m pretty sure I’m done w speakers, now amplification on the other hand, I’ve got 4 right now, selling 2 and shopping for another. 6 if you count receivers.  I can’t stop, I’ve owned dozens.  

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.

My Wilson Audio Alexia V’s. 
 

Woots

Keeping what we have but I want to give Magnapan and open baffles a whirl maybe even a open baffle kit. 

I have been upgrading loudspeaker Xovers for over 20 years .

in your revels the parts quality is a average at best !

meaning maybe a 7 out of 15

just pull a driver out and you-can see inside not even a name brand Taiwan  on some capacitors.the resistors are $1 , when top quality even $12 mills are much better . The Xover is the 🧠 or ♥️ of the Loudspeaker . As much as you think it sounds good a upgraded Xover would’ve at minimum 10% better still. Look at  Humble homemade hifi capacitor test. For all capacitor ratings to prove my point.
