As part of our commitment to providing a lifetime of enjoyment from Ayre products, we are releasing an update for the QB-9 with the newest technology from the 8 series. The “Twenty” update for the QB-9 brings it back to the cutting edge of technology, giving QB-9 owners the excitement of discovering their music library all over again!
