Has anyone discovered SONOS wi-fi speakers? My 40 year old amp and receiver has the inputs going out, so I decided to up grade to a new bluetooth system to compliment my xm radio,soo I bought a bluetooth system and set it up, while doing so I found SONOS which happens when one thinks they have found the best solution to a problem. Any way SONOS is wi-fi streaming, can be connected to 34 different speakers in 34 different rooms each can control 34 volumes seperately and play 34 different formats on 34 different stations, and can be controlled by your laptop, tablet, phone, together as a singal unit. Contains iheart, pandora, and more free and subscription apps, speakwrs range from 200-600 to tv bars 1200 on up. I like mine.
