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.

Shalmaeser, I would try this before dropping big $ on an optical cable.  I think the optical converters on both sides usually don't merit the added expense of a fancy optical cable compared with coax cables.  This inexpensive cable is all glass and works very well in my experience, better than much more expensive synthetic fiber cables.

@knownothing Thanks for the link. I never did buy into the super connector concept at any level, even in the copper wire days - and my research into audio fibre optics confirmed that. There are minimums of fit, finish, and conductors required by communication standards. However that doesn't mean manufactures haven't been reading their P.T.

Looking at pre/pro's. Bizarre that I can find a Meridian 568 for $600 with a $6,500 MSRP.  Reviewers consider it neutral - which I consider a plus due to all the other possible coloration.  It also has some balanced outputs. Might buy it just to own something that's well into 4 figures.
I've found an anthem 50 that's sub $1000.
Outlaw 990 goes for $250 with an $1000 MSRP. Seems to be in the same class as the Anthem. 
Anyone with more suggestions based on the NHTs and the Anthem amp?
