With the Orbs in the equation, I suspect that the 7075 would be a great fit for your system (and the 970/7075 deal they've got going this month is pretty tempting). The 990's a definite upgrade according to the folks who've heard both, so either a 990/7075 or 990/7125 package would be an upgrade from the 970/7075 - of course the price tag's correspondingly higher (especially in light of the 970/7075 special).

Have you got the 1070 running in the bedroom setup yet?
