DMF,
I am a big parasound fan: I use two 2200IIs, 806, cdc1500 changer, and have owned 1500A, 1205A,800II amps and the excellent dac1600. I also used your psp1500/pdd1500 (I had the pdd1550 with dts) for a few weeks recently as my Aragon Soundstage was getting upgraded. I am not a big Outlaw 950 supporter LOL

....but I think the 950 would beat your Parasound combo in most areas...DPL2 and the 7.1 modes are much better than DPL and 5.1 if you can setup 7 speakers correctly. 2 channel performance is not great...IMO, you should buy the 950 and try it.
On the amps, I would keep your Parasounds and just add a 2 channel Parasound (ie, a 1500A 205x2 or 1000A 130x2) to drive your mains and round out your 7 amp channels. Why sell your nice amps at a discount and buy new amps that are a lateral move? That's not good economics. In fact, you can probably find a used 2 channel Parasound on ebay.
IMO, with your emphasis on 2 channel, I would suggest the following:
- Parasound 1500A 205x2 (~450 used)
- Outlaw 950 (799)
- used Rogue 66 Magnum tube preamp with HT bypass unity gain (~ 800 used, see Audiogon.com)
