@lfromsalem Check out the Paradigm Founders speakers, then report back your findings/preferences. This would help us to narrow down other choices. The Paradigm Founders got great reviews, seemingly a high value choice.
A used Hegel H360/H390 with the DAC is a popular/safe option.
Agree - choose the speaker first, then compatible electronics.
Preamp+Amp vs Integrated - A separate preamp, amp, and DAC may make more sense if you plan to upgrade individual components later, but is more costly in extra boxes and cabling. An Integrated is a better economic "value" but cannot later update individual components.
I'm excited for you - a $9k speaker+integrated update should be a major sonic uptick.
Demoing speakers is best, ideal if in own system. But finding local stores can be difficult. I demoed high-end stores in SF Bay Area and LA area, went to major audio shows like AXPONA, T.H.E Show, RMAF (RIP), Pacific Audio Fest before choosing my speakers. I purchased an AXPONA demo pair.
