I have a feeling it will be a while before we see receivers doing 9.1 PLIIz. What they'll offer instead is the choice between doing 7.1 PLIIx with rears, or 7.1 PLIIz with heights.

Either way, since ProLogic is all about ambiance extraction, and the QSes are excellent at reproducing ambient sounds; I'd say a pair for the hight channel may be the way to go.

We'll have to wait until 'z' receivers are in more people's hands and we get some listening reports for a subjective answer rather than a guess.
