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

Quad ESL-57s. What could be more musical? They are almost 50 years old and sound as lovely as when I purchased them. They are run with a good AudioNote tube integrated amp and give me joy every day.

I was just thinking about doing that, but I'll let you handle it 
It will be interesting to see which ones are the most popular. 

My Klipsch LaScala AL5 speakers! They are seriously dynamic, incredibly responsive and lightening fast. And absolutely gorgeous! 

No plans to replace my AR9's as I've been happily listening to them for 25 years. I have a pair of KEF R107's for back up if the AR's ever need repair. For the kind of listening that I do anymore, either suit me just fine. A lot less hard rock than I used to listen to, more likely to do Celtic, classical or neo classical these days. I find what I consider to be beautiful music (female vocalists, piano, synthesizer, strings and the like), to be much more soothing in my old age. I still like it loud but not crazy loud like I used to in my youth. I love deep bass from piano, synthesizers and pipe organs and either of these speakers do that all quite well.
