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

My collections stays Diapason adamantes musical and very nice looking, Andra eggleston it took me 15 yrs to make them sing using 150 watt tube monoblock, Technics  monitor single driver cabinet is state of the art musical as well, KLH model 9  collector items as well modified by the late owner, Red rose  r3 stays as well love the design they also disappear, My omega rs8 birch the cabinet and the musicality is insane. My Borensen x1 onother collection of mine my retirement speakers. I will keep my two Tekton as well.So none for sale. 

Jcatdcat Moab are amazing speakers especially if you have the right gear for them. I own ps12 and the impact monitors , I heard them at my friend house using Aric gear and audio mirror t3 dac Iam very impressed.

Rogers LS3/5A is hard to beat for a small box. I first heard them around 1977 at my local HiFi store. The price then was $450. At the same time the Rogers JR149 were also $450/pair at the same store. Same KEF drivers, different crossover. I liked them too! 

I didn’t buy a pair until 2017 - an eBay seller in Lithuania had a pair for $960 shipping included. Serial numbers 39269A and B. Walnut finish. 11 ohm’s. 

Falcon in England has an anniversary edition of 100 pairs at $10K.

My end game speakers are Zingali QA 3.8  

Empirically proven to be my Polk Audio SDA SRS2 set I bought new in the 80's.  I've had them longer than my wife of 35 years and every place we've lived needs to accommodate their considerable size and heft.  They are still the speakers for my solid state setup and are augmented with a Polk Center and Surround setup for AV use.  They are very musical, reasonably transparent, and capable of full range volume levels that make your chest resonate (Helicopter Rescue scene in The Matrix...  holy hell!).
