I have both 7.2's and 3.6's and the only thing I'd ever think about replacing them with are Tidal Contriva G2's or Agoria's. They're that good.
Thats a big statement 3090 and I agree, I have spent some time with Tidals. I have 3.6 (my favorite) and CS6. Mcintosh 501’s drive them good, Classe CA200 drives them better.
I ventured off track a few years ago with Egglestons Andra II’s because I admired them years ago but I could never keep the Thiels out of the system. Hard to switch speakers when you are so accustomed to the sound and performance.
