Marco, You should have mentioned your 3 Systems from the Go-Go. I can understand the whole Kitchen system issue as there's Bacon grease splatter concerns.
I have owned most of the Bryston line-up, yet never had the need for one of their Switch Boxes. I do recall them also having Impedance Protection, as the Bryston units are built more robust for the pro-audio venue then the Niles units. The Brystons are made to handle wattage levels that their 7bst, and 14bst amps can crank out.
Getting to the bottom of your Switch Box question would be a worth while call to James Tanner at Bryston who would but your mind at rest. I would venture to say that your still running the same 8 ohm load, just splitting the wattage.
But then if it where me, I'd pass on the Switch Box entirely. I'd modify a ceiling hanging fruit basket to suspend a 4th system in the Kitchen. Then throw on some Billie Holiday, and enjoy my new Strange Fruit System Suspension Swing.
