Good ideas!
Gonk, the gizmos you pointed to are about $50-100, and a nice looking
Niles HPS-4 costs almost $200.
With that in mind, the bottom of the line Denon AV receiver, the
AVR-587 , is only about $250 factory recertified, and for that you get 75 watts x 7 channels, etc, etc.
Hmmm... here's an idea, a VERY highly rated factory recertified Denon
AVR 3806 for $700 and the AVR 587 for $250 is only $1050 and you should be able to configure a zillion speakers, zones, etc with your 14 channels!!
That is a little more than the cost of the Outlaw 1070, but a lot less than any of the Outlaw separates if you want just a set of B speakers. (You *need* the 990 at $1099 just to get B speakers!)
