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

Wilson Audio Watt/Puppy 8's in Ferrari Blue.

Your in between speaker becomes your endgame speaker if you can't find anything that's better in all respects. Got Eminent Technology ET8's in the last century and now they're upgraded to the Super 8 (added backward firing woofers). 

So happy to see open baffle speakers mentioned. There's no box like no box. Even on YouTube, you can hear the difference when you get rid of the box. Planars like ET8 or Maggies are naturally included.

OP: could you post the rest of your system in the Systems portion of Audiogon? 

Any Tocaro!!

(depending on your budget. The 40s would totally do it, but I’m lucky enough to be able to afford the 50s…)

just make sure your amp can deliver ….

I think I have my "forever" loudspeakers in my custom built Linkwitz Orions.  I've never heard anything I like better for voices or acoustic piano.  They have exceptional dynamics as well. 

My listening space is quite large - 30'x42'x12'.  That's a big room.  The other day I was playing a record of Art Blakey and the Jazz Messengers at full live levels (my wife was out of the house).  I caught them live many times back in the 1980's and I KNOW that sound.  The Orions delivered full dynamics, excellent imaging and detail in a room much larger than most listen in.  That's saying something.

There are other designs I feel audio lust for, but when I crank up the Orions like I did the other day, that lust goes away.  There are other loudspeakers I'd probably like better, but the Orions sound so good I don't care.

I’m extremely happy with my Dynaudio Heritage Special’s , don’t see myself changing them. I can listen for hours with no fatigue. Also at 64 I don’t want big speakers that I can’t move. I live in a smallish apartment, expect I will never own a big house again. I’ve been using the Dynaudio’s with a REL S/510.. even that’s too big. If I can’t move something myself I’ll have to pass. I plan on selling my S/510 and probably getting REL’s new Classic 98.
