What are the speakers you very rarely find in the Used market(Audiogon or Anywhere)?


I'm looking for Vandersteen Quatro CT, Wilson Sabrina or DeVore Fidelity Orangutan 0/93 or 0/96. I rarely find it or in some cases, before I make an offer, it is gone. What other speakers are a rare find?

Have seen one US pair of Devore Gibbon Xs in 3 years...sold in like 48 hours.
I mentioned that Sonus Faber Extremas rarely come up for sale. I dropped in to LMC Stereo in Scottsdale, AZ yesterday and there they were. They were around $10K when introduced in the 90’s. The new version are $70K (new, $65K used). They are gorgeous, but the price is shocking (to me, anyway).
ACI Jaguar 2000, ACI Emeralds. I have the Emeralds, heard the Jaguars are awesome!
