....but I figure I've bugged him enough lately and would just post it here for some help

I must be the luckiest guy in the world, because my wife is actually encouraging my upgrade-itis. This is truly unbelievable......anyway....
Here's where I'm at:
I just picked up an Outlaw 950 and three M200's (these are the coolest things I've ever seen) to take care of the fronts and center. I have a Parasound HCA-855 that I've been using for the surrounds, and was planning on using for the rears for a 7.1 configuration. Okay....so here's the deal. With Gonk's help, I have made the decision to order a pair of Paradigm Studio/100's and a studio/cc. I've also decided to add some studio/20's for surrounds. My wife says that the surround sound just doens't cut it for her, and she thinks we need some more power back there. (Yes, the system is calibrated with an SPL to 85 db.) She says, "why don't you just get some more of those cool mini amps and get rid of the Parasound?" So naturally I got to thinking......maybe a couple more of those Mblocks would do a nice job with the 20's when I get them. One stack of three looks pretty damn cool, so maybe two stacks would look even cooler....not to mention the fact that we are both thrilled to death with the sound. Okay.....the 950 is 7.1......but my wife says that she really prefers we don't go more than 6.1, since we are only wired for three in the back. Given that I won't be going to 7.1 any time soon, I'm thinking maybe adding three more M200's wouldn't be a bad idea! I could add two more now and stick with 5.1, and then when I track down an additional studio/20 for the rear surround, I could just add another M200. So what's the problem? Well......my Parasound is only about two months old, and even though I really, really like it, it's only 85 wpc. I initially got it to pair with my 1050 (and it was an awesome pair!), but I've had a financial window of opportunity to upgrade and have gone Outlaw and Paradigm crazy lately. So......do you guys think I should just stick with the Parasound (i.e. 85 wpc is sufficient for the back) or should I move the Parasound and pick up a couple/few more M200's???
Any feedback would be greatly apprecaited.....Happy Listening!!
