Hopefully simple question. I have the new Sonos Amp with a wired connection to two Klipsch bookshelf speakers. Sounds great. I was considering adding the Sonos subwoofer. A recent review in PC Magazine indicates, however, that the wireless Sonos Sub will NOT work with the Amp when the Amp is powering two non-Sonos speakers. In other words, given my current setup, I will have to go with a non-Sonos subwoofer.
Is this correct?
