it was an single offer from a private citizen.
But not on ebay.de
In Germany wie have also ebay-kleinanzeigen.de
I don’t know what it is in english. But I think 77€ is also a good price. It gives Airplay-Speakers from many other manufacturers. B&W, Logitech, BOSE, Teufel, Panasonic, Sony, Boston Acoustic etc
Also all Yamaha MusicCast Components are be able to user Airplay
