I have the 3802 and I would assume Koiman's setup is
center vp150
Main l/r and rear l/r = M80
Surround A = A pair of qs8
Surround B = another pair of qs8

Denon uses Surround A as the 7.1's rear channel. (and multizone if u set it as the 2nd zone)

I am also curious that many people mentioned to use qs8 as Rear Left/right and then use a more direct speaker at the back, is that the best setup? If I am correct, then one who use denon w/ 4 m80 and 4 qs8 should set
M80 as main Left/right and Surround A
Qs8 as Rear left/right and surround B
