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.
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?
