Power Amp suggestion


Would love to hear recommendations on replacing the power amps in my system. Current system is Roon Nucleus+ Server, Chord DAVE DAC, Audio Research Ref 6SE, Bryston 28 SST2 monoblocks, B&W 802 D3. Cables are all Synergistic Research Galileo/Atmosphere . Have not heard the Swiss uber expensive equipment but would Soulution or CH Precision make any sense?

I tried  bryston amp with arc ref3 and did not like combination of it.Arc sounds neutral,bryston neutral.Either amp or preamp needs to be changed.If for amps I would look to something warmer souding or warmer fuller sounding preamp
Someone on here recently (maybe @erik_squires?) said try and listen to 3 amps...Ayre, Luxman and Pass.  They are different presentations. I wouldn't say to choose one of those but you will probably like one more than the other two. That gives you an indication of what sound you like and people can give you better and more accurate advice. 
I would consider speakers before amps too, that may change your direction on amp selection too.  Unfortunately the B&Ws are very hungry, you need a lot of power for those.  A big Pass or McIntosh would be nice.  I think the big name Swiss brands are very overrated (I’ve heard many).  However, I would consider new speakers that are more efficient and then replace the Bryson with maybe an ARC Ref160.  
How do you like the DAVE DAC?  I’m considering one.  Are running the Nucleus into the DAVE directly through USB?

while Bryston may build something to last 20 years, McIntosh builds to last a couple of lifetimes.
