FWIW, my son used to work for Bose and got a lot of their stuff as reward for "attaboys" at work. When he was first putting together a surround sound system, he had an Acoustimass 5 system he'd won at work and tried it. He had a Sony AV receiver and did get it connected somehow, but hell...that's the job he had at work.
Then he bought a pair of KEF Q300's. He couldn't get rid of the Bose system fast enough. Sale of it funded a Q200c center speaker. Weeks later, I showed up with a pair of Q500's, which replaced the Q300. He tried using the Q300's as surrounds, but ended up getting a pair of Q800ds dipole surrounds.
Months later he picked up a pair of Q100's cheap, and got a Rocketfish Wireless transmitter and receiver-amp setup at Best Buy to run them as rears. Too far to run wires to the back of his 25' long room, that Rocketfish setup is still working great, all dialed in with Audyssey.
My point is that even a gung-ho Bose employee was easily converted, and wireless surrounds are possible on the cheap.
