I don't think it is possible but I have B&W 602's on a Sony 930 AV amp. I currently use it for music as well and was wondering if I took my record deck of the amp and put it through a valve amp with a phono stage. Ideally i would use another set of speakers but I don't have the room I could then thought about connecting the valve amp to the 602's as well as the sony amp. I would have to take the metal plate that goes between the two sets of speaker wire connectors at the back of the speakers. I then would use one amp at a time. Or would that blow something up.
