So basically the second possibility i mentioned is what is happening.
The Denon folk are allowing users to run both surrounds off a single amp channel but there is inherent danger in doing this.
As you mention John, running the second set of speakers off this channel will lower the impedance by half which is really going to work the receiver pretty hard. If anyone did not keep to the strict spec of using only 8 ohm speakers in these surround positions, they may begin wondering why the receiver keeps shutting itself down.
Has anyone tried this full 9 speaker config with the QS8s or any other 6 ohm speakers?
