More detail, faster would be nice.I wouldn’t be looking at changing amps if that’s what you’re looking for. If you really need a change I’d focus on speakers as you’ll get the biggest change, and IMHO speakers from Joseph Audio, Vandersteen, ProAc, Usher, Nola, Magico, YG, Wilson, Avalon, Audio Physic, Boenicke, Vimberg would all give you more significant improvements than swapping amps. IME B&Ws are detailed but clinical sounding and not nearly as musically involving as any of those listed above. I respect B&W speakers but can’t love them, but that’s me and clearly many others would disagree. Anyway, best of luck in finding whatever it is you’re looking for.
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?
