Why so many Gallo 3 or 3.1 for sale on A'goN?

For a speaker that got rave reviews...there are sure a great number of pair of the Gallo Ref 3 or 3.1 being sold on AudiogoN.....usually with just a few months use. It's not just the ones for sale now...this has been going on for a few months.

Do these speakers just not sound good after a buyer listens for a few months or what?
