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.

Thanks for the links. The odds are good that the 8.1 drivers will work just fine - and probably why they haven't invested in updating them. 
Shalmaeser, I am assuming you are questioning how Tidal could sound similar to Bluray (or 24/196 files)?  I will try to clarify.  Hi Res material generally sounds better from both multichannel Bluray (HDMI) and Hi Res 2 channel FLAC or AIFF formats (USB), but the general overall character of the sound of Redbook (CD/toslink or files/USB) or "HIFI" quality Tidal streaming source material (USB) is closer to Hi Res sources compared to Redbook from CDs via HDMI in my system.  Make sense?  I find Tidal can sound pretty good.  Clearly better than MP4 or Similar, if not quite as good as Redbook from CD of files for the same content.
@knownothing I'd not heard of Tidal, and now Redbook. Googling around a bit found the CD standard definition for Redbook. Tidal yielded a website of music. Thanks.
