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

Magnepan 3.7x. 

I’m really loving my Charney Audio Companions with Voxativ AF2.6 drivers. Powered with very upgraded custom ANK gear. I would only replace them with the Charney Lumaca if I moved to a larger listening space. 

ProAc Response 3.8

I don't know if anyone here even knows of my "keeper" speakers because they are rare. Amrita Audio Reference Standard Towers. They have a 13.5 inch, paper cone cast frame woofer, dual 6.5 inch DynAudio midranges with 3 inch voice coils and a Vifa metal dome tweeter. They're about 48"x14"x16" and I scored them at a local Salvation Army store in 2021 for $500.00 pr. 

I think Zellaton is my last speaker, but i’ve said that before. They have a wonderful blend of speed, transparency and natural sound. If I was tempted by something else it would probably be Wolf von Langa.
