Picking an amplifier


I have the following speakers:
NHT 2.1 Front LR 200W @ 6ohms
NHT AC1 Center 150W @ 8 ohms
NHT SW2 Subwoofer 200W @ 8 ohms
The rear speakers are inconsequential (and boxed up) they might come out to play when I move to bigger digs.
I’ve been using NHTs 214s and 216s, (think lightbulbs) but the market is drying up. I remain unconvinced they are worth the shipping & costs to repair.
My (current) short list of replacement amps:
Outlaw Audio model 770 7 (7 channels)
Bryston 9B ST (5 channels) (2 years left on warranty)
Parasound 5125 (5 channels)
The budget is $1000, I have located sources for all three at or below $1000.
Any/all discussion of suitability, repair outlook, and peanut shells welcome. From a listening perspective, I've been fine with the NADs, but am priced out of the newer models. Nuts, I might even repair the NADs if I find the right person with the skills & tools.

Out of your choices, the Outlaw is the highest current, largest power supply amp.  It's really hefty coming in at 90 lbs with a large shared power supply.  The Parasound is the newest (but not by far).  The McCormack may be the best sound quality - but you would really need to research this.  The NHT 2.1 you indicate as 6 ohms, so they may actually drop down lower.  I would probably lean towards the Outlaw amp unless somebody has a definite opinion that McCormick is better sound quality.
Thanks imhififan. That’s an interesting amp.

Update: That's a typo on the NHT, they are the NHT 2.5, not 2.1. (In case anyone searched)

Additionally, my source is the Sony DSP-EP9ES optically connected to my Z170-A (LGA1151) motherboard. Apparently the source matters to some amplifiers. 
Auxinput: The Bryston's also a heavyweight: their multi channel amps range 75+ lbs. Weight isn't a problem for me. So far the  McCormack appears to be the most thermally efficient of the group. This guy fully dissected the McCormack http://www.iar-80.com/page67.html from the view of a full on audiophile with very deep pockets. The reviews of the Bryston show some inclination of being too bright in the highs, but that also could be a function which speakers are involved. 
Shop long enough and you end up spending all your money. Anyone have direct experience with NHT speakers and Sunfire? Which Sunfire would be the best acoustic fit?
