I read a couple of reviews, one on CNet and the other I think on iLounge, but might be wrong on that one. They weren't raving about the speaker, given its rather lofty price, more than the Bose sound link 3. Also, one review I saw said that they had problems maintaining the bluetooth connection, just as they have had with airplay offerings from B&W such as the Zeppelin. I never owned that one, so I can't comment one way or the other. My only recent experience with B&W has been with the MM1s, which I love and with in wall speakers in the home we lived in a few years ago; those were also fantastic for what they were.
Would love to audition the t7 before laying out the kind of money they want for it. Mary
