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.
