With great regret, I posted listings to sell my remaining Sonos gear today. Although I regard the company and equipment as some of the best in the industry, there is simply no need for it in the new house because of the sound systems connected to our TVs and the open floor plan. I worked at Sonos as the head of engineering during the development of the Play5, pictured above. Of the 100+ products I helped to develop, this is one of my top five favorites.
