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

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. 

I love my Klipsch KLF-30s and my B&W 802s.  The 802s I had since the 80s when I was in the military stationed overseas.

I have a pair of Tekton Symphonies, which are a variation of the Encores. They are configured more like the Moabs, with woofers on the top and bottom of the cabinet. I’ve had them over two years and every time I fire them up I have a hard time turning them off so I can go to bed. They produce the most realistic sound I’ve ever heard. I have listened to several systems in the area that cost 10 to 15 times what I have invested and I still like mine best.
