What speaker is the most musical, one you never want to sell?

3. A sound that allows a maximum enjoyment and engagement in the music itself.
And of course, musical systems are the ones that keep your butt glued to your seat and you just can’t stop listening and you find yourself many hours later trying to drag yourself off to bed :-)

That's exactly what I'm looking for.
However, as this thread is pointing out, it seems to be different for everyone. 

Black Swans.

Though I've kept the boxes for my 2023 KEF Blade 2 Meta speakers, they're really for my heirs to be able to sell them off and not me.

:D

I have llistened to a bunch of speakers over my audio journey.  I really like the Vienna Acoustics Liszt which I own or The Music.  They just render music in a beautiful manner with extension, bass, soundstage without getting too analytical.  I just want to listen to the music and not analyze every single sound that may be out of place.  When you listen you know when it's right.  So many speakers sound impressive on first listen but get on my nerves after a while.  I'm not an inexperienced listener and listened to Kef, Borreson, B&W, Magnapan, Wilson, Harbeth, Dynaudio, Vandersteen, Magico, Rockport, Focal, Sonus Fabre, Golden Ear, JBL, Genesis, Joseph Audio and more that I have forgotten.  I would circle back on a couple of models such as the Rockports, and Joseph Audio if I was in the mood for an upgrade put I'm not.  The reference line can play everything well.
