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

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. 

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

Duntech or Dunlavey speakers rarely seen.

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

Salks are rare as hens teeth!!
