I checked out the audioengine w3s. It might work, but we'd need to get USB powered speakers as well. We already have a bluetooth portable speaker logitech S-00096. Does anyone know of a bookshelf system or receiver, etc that broadcasts bluetooth signal? I've only read about those that receive the signal from an ipad, etc. I'd like the receiver or soundbar to issue the bluetooth signal and then use the system's speakers, PLUS the small bluetooth speaker next to his chair. Any ideas?
