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

GOOD ONES.

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 ?

Technics SB E200.  

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.

While I like to hear how other people combine amplifiers and speakers, Magnepans closed my mind to anything else.

Never seen a used pair of Sonner Audio speakers

Gradient 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.

JBL 4350   Fortunately I own a pair.

Boenicke 

German Physiks
HHR Exotics
Huff
Ohm Walsh A’s

Field Coils from Classic Audio Loudspeakers!

Klipsch Jubilee 

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!

Usher DMD2
excellent speakers.

+3 for Aerial acoustics!

Dunlavy sc-v.     Last pair I was on ebay sold in a under and hour. For 10k    I have 2 sets of sc-Iv and been looking for the 5s

Also jbl 250s.   Been looking for those forever 

Apogee Scintillas, Wilson X-1 Grand Slamm, Martin Logan Monolith lll, Avalon Isis, Infinity IRS.

Vandersteen Quatro CT Available Used $12,500.00 Customer upgrading.
Vandersteen pricing is going up. Quatro will be like $18K. You snooze, you loose....
I have a Pair of T+A Solitaires for sale 1000SE In Carbon fiber. $32000.00Dealer Demos.
Vandersteen Audio gives very little mark up as they are priced very conservatively in the market. Richard is the Costco of Audio. Other manufacturers would have priced the Quatro for over $25K. Buying them retail is a bargain.

Original Gallo Reference II's 
Or what some audiophiles consider an even better sounding speaker:  Nestorovic 5AS Mk IV

Fat Julian in Atlanta told me about the Fuselier speaker...never heard them.
i miss his record shop.

How about Harmonic Precision...

Here's a beaute...I have NEVER seen a single used pair of T+A's amazing electrostatic hybrids, The Solitaires, for sale!

Any Magico model! Especially considering how many are sold in the USA, it is very rare to find them used.

Fuselier
Went out of business many years ago but John’s speakers were way ahead of their time and in some ways remain SOTA. John recently passed away and I count it a privilege to have known him back when he was designing and manufacturing loudspeakers.

MBL 101 radiostrahers, one of favorite in the world 
and big Marten Coltrains.

Yankee Audio

Audience 1+1 V2's...  Rarely seen used.

Salks are rare as hens teeth!!

Dynaudio Special One. Not when they were young, not when they are a quarter century old.

Duntech or Dunlavey speakers rarely seen.

My advice is to buy, when U C them, instead of a lot of talking.

There have been a few pair of Wilson Sabrinas lately. Have only seen two pair of 0/96 in the past year, and one of those wasn’t here. A few more 0/93.. Two pair of JA Puslars popped up in the last month or so and were gone fast, and one of those was a realist. That pair of JA Pearl 3 had been on here a couple times in the past from the same seller, but at higher prices. Have seen just two pair of Quattro CT’s in about a year here. 

Three_easy....yep I’ve been keeping my eye out for D7s or D9s for some time now, rarely happens. I think it’s because there just aren’t lot of them in the US, plus owners hang on to them. 

Snellc5 bought them in 1997 still listen to them ever day. Just purchaset a McIntoch MC452 can’t wait to get it hook up to old Snells 

XStatic full range electrostatics as there were less than 100 pairs made (awesome sound BTW).   Triangle Stratos Volante 260 is another great speaker as was Gale.   I also don't see a lot of Ohm's higher-end speakers for sale.   All of which I still own or owned.

Agreed on Aerial Acoustics!

Tannoy

Tidal Piano. I have yet to find a pair.

Just buy them next time they pop up and don't wait around making offers. Others are just buying them for the price listed and might be the price you have to pay for rare used speakers. I did that with a pair of 0/93's

Fritz 

Any mbl speaker.
Any music culture speaker.
Diapason rarely but have seen 2 pair in 4 yrs. 

@simao    Gershwin ? I think you meant Gershman ?

I have seen recently only one pair of Pulsars up on the 'Gon. I have not seen too many of them for sale here or elsewhere. I could be wrong, but that is my experience.

Tetras!

MBL 101 X-Treme
MBL 101E MKII
Martin Logan Statement E2
Apogee Studio Reference

You don't see a lot of Aerial Acoustics out there. I'll never sell mine.

You can find plenty of Joseph Audio Pulsar's available but finding the Pearl's/Perspectives are tough. Was recently a pair of Pearl 3's here on Audiogon and they were snatched up in 2-3 days for 18K.

Any model from Joseph Audio ... people tend to keep ’em.
