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?

Just about anything that Fried designed and sold.  They are a very rare find for sale on the web.  I have a pair of custom Fried C6 TL speakers, and I know why they will never be put up for sale.  The vast majority of Fried owners will not part with their speakers!
acoustic preference gracioso 1.0 and 2.0 are difficult to find. If you ever get your hand on one, you will be blown away.
While I like to hear how other people combine amplifiers and speakers, Magnepans closed my mind to anything else.
Preowned Wilson speakers are VERY common to see being sold very much including the most expensive production models (XLFs as you read this on AG & virtually everything else) - however in all the decades the WAMM has been made, I've never seen a single one come up for sale.  All 7 versions (not including the Chronosonic which is arguably too new).  Something peculiar there.
Getting ready to sell my Aerial 8s for Martin Logan ESL 13A.
Made 70 on 3/10/2019, with hearing loss...”dying” to make one more change before I hear the trumpets call. Am I making a mistake ?

Someone still hankers for a pair of ML Monolith IIIs?  I sold mine 20 years ago and good riddance, slow bass, directional, limited dynamics.  Replaced with Legacy Focus.  Music preference is opera, jazz, classical and pre-1980's pop while wife also wants to enjoy heavy metal and raucous rock.  Focus speakers suit everything while Monoliths had limited appeal even for my tastes.  Generally rarely seen are Acoustats (I had 2&2s), especially Xs which were deemed the big coffin speaker by my late wife. 
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!

Windmilldad: I own ML 13a. (I can speak from experience having been an audiophile for 5 decades.) They were very good speakers when matched with reputable amps and preamps. A year ago I took it to the next level and went with Don Sachs tube preamp and Krell’s 575 XD mono. Now they’re a great speaker, I can’t imagine better SQ. Two important items when working with the 13a, the amp needs plenty of power and the preamp should be tubes. Enjoy. 
The be-20 dmd’s Are excellent speakers and I have a pair of them along with a pair of DSP8000’s and I have to pick 1 to keep, you would think that the $65k speakers would trounce the $20k ushers and I wish it was that easy but those big ushers have a lot going for them and when we factor dollars per smiles the usher speakers are a bargain.
I've never seen a pair of Vandersteen 7 Mk. II and rarely see 5a Carbons on the used market.
Vandersteen Prices are going up by 10%-15% based on models. No Exceptions ! Done Deal ! You snooze, you lose. April 2nd.

The previous generation KEF Reference speakers seem rare on the used market. I have a pair of 207/2's and the 202/2c center speaker. I have seen maybe two pairs each of 205/2's and 207/2's advertised in the last few years. I see the first version 205's and 207's occasionally.
I also just got a pair of Wilson Audio Maxx 1 speakers great buy for someone who wants big bass...
I sold my lovely pair of polk lsi9's several years ago.  Regretted the decision.  I found another used paid but took a long time.. They are hard to find, but well worth the hunt. 

You might try a pair.  Perhaps in the $400 to $700 price range.  You can always resell them.  They have way less of a port problem than the Kef Ls50's (which did not work in my room - puffy low-end did them in).  drumbe
Clever way to find out which brands keep owners the happiest.
Thanks for asking!
I see Magicos here all the time. There are 10 for sale as of this writing. Another brand I hardly see here is Reference 3A.
@jeffreylee - Vandersteen Quatro Wood CT came to market this morning  but the seller prefer local pickup. I spoke to the seller and told him I'll take the responsibility of shipping even then, it was sold before I got the shipping Dimension :( 
Ya.. I agree with You Bro....

Back about a year ago my dealer had 3 pairs of Aerial 6's (one set was mine). All trade in's for the new T series. They were all gone in less than 2 weeks. If your into HT try to find an Aerial CC-3 or CC-5.
