I was unaware that the 1009 can do the 3 configs without re-wiring. I have a 3009 and can confirm that it can't be done that simply. With a 3009/5009 you can wire and select easily btwn FW/RS or FH/RS, but not FW/FH. To do that, you need to manually change the speaker wiring config as the signal outputs change for some reason. Very inconvenient if you have a full 11.1 setup as I do. I have ended up leaving it wired for FW/FH as that sounds best to me, but miss using my nice rear surrounds. The side surrounds do a nice job and I don't really miss any rear enveloping sounds, but the dedicated rears are permanently mounted and I would like to add them in.
