To Focal or not to Focal

The Aria sound sweeter to me than the Chorus in this video. There are also differences in room acoustics - no panels with chorus and a ton of room reverb. Who knows what else is different.

@erik_squires good points about the Focals being power hungry and the room acoustics.
I used to have DNA 0.5, DNA125 and 225. All are great amps. I also owned Rogue ST100 with RP1.
It’s been a long time, probably 20+ years since I heard those NHT speakers, but I still have the AC1 center channel that I just recently replaced with Focal Aria CC900 purchased together with the standmount Aria 906.
The CC900 is a better speaker than the NHT.
And the Aria 906 have definitely surprised me in a good way, driven by a Marantz AVR.

So my recommendation would be to upgrade the speakers. Keep the RP1/DNA1 combo. I think you’ll like the Focals - they’re warm and very engaging sounding speakers.
