Anthony,

I am currently at 9.1 with wides and heights and I highly recommend it.

Audyssey DSX is awesome and will be even better with 11.1

I would suggest M2's or M3's for your wides and maybe QS8's for heights. JC here at Axiom uses the QS8's for Heights and has great things to say about that setup. FYI
