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

Yes! Pure Audio Project Trio15 Horn1 for me.

I love 'em. I've stopped looking elsewhere.

I currently have AMRITA AUDIO REFERENCE STANDARD speakers. They are the best speakers I have owned. I really liked the Alta Audio Adam but at 18k I will never own them. Several offerings from Von Schweikert would also be on my radar when I win the lottery. But I'd be TOTALLY happy with the unbelievably high value and moderately priced Tekton Moab.

Quad 63s and Quad 57s.

PBN Audio EXP speakers for me. To better these would require a tremendous amount more money. 

Legacy Audio Focus XD. Thoroughly happy and content. Along with the Wavelet 2 DSP/EQ. I auditioned multiple speaks and for the price point (15k] there are simply no other contenders to get me where I wanted to be.
